TypeError: Use 'delete()' to clear values

Hello, This morning when starting Armored Warfare (from Epic store) I got the following error:

===
(09:13:39) [ERROR]: An exception occurred when launching the game:
(09:13:39) [ERROR]: TypeError: Use

I want to add that the game worked perfectly fine for the last two years. Any help/pointers would be appreciated. Thx.

Just posted the exact same issue with Deus Ex - Human Revolution:
Deus Ex - Human Revolution (GOG) not running anymore from one day to the next

spontaneous-moccasinOP•12/14/25, 3:46 PM

Just to add, running on OS: Linux Mint 22.2 (Zara) (linux)

embarrassing-maroon•12/14/25, 3:47 PM

seems it's the same error as 🆘-supportSilent Hill F won't run as well (i'm having the same issue with all my heroic games atm so i just followed all 3 threads)

full-green•12/14/25, 3:48 PM

Linux Mint 22.1 in my case.

brilliant-lime•12/14/25, 3:48 PM

22.1 as well

embarrassing-maroon•12/14/25, 3:49 PM

I'm on Bazzite 43

spontaneous-moccasinOP•12/14/25, 3:50 PM

I just checked my OS "Updates" for the last two days, and nothing that sticks out.

Eembarrassing-maroon I'm on Bazzite 43

brilliant-lime•12/14/25, 3:50 PM

I'm just gonna assume you mean the latest version of Bazzite, because that's not a real Bazzite version number

inner-olive•12/14/25, 3:50 PM

same error here with cachyos and watchdogs2 from epic

clean-aquamarine•12/14/25, 3:54 PM

Same error, latest Bazzite 43, no changes to the system, no idea why this is happening

spontaneous-moccasinOP•12/14/25, 3:54 PM

The Internet search comes with the following explanation of the error, not sure if that is relevant in our case. But could possibly help.

The error message "TypeError: Use delete() to clear values" typically occurs in programming environments that utilize data storage libraries, such as Electron or similar frameworks. This error indicates that an attempt was made to set or modify a value in a storage object without first clearing the existing value.

(game: KB Dark Side)

embarrassing-maroon•12/14/25, 3:55 PM

mb, first time using linux, i just checked the firmware version, using command console it says version 43, you're right

inner-olive•12/14/25, 3:55 PM

bruv this launcher is so rage bait i had to reinstall watch dogs 2 yesterday 2 times still no work even today with a fresh install of watchdogs2

clean-aquamarine•12/14/25, 3:55 PM

yeah, the launcher seems very... fragile

brilliant-lime•12/14/25, 3:57 PM

The launcher is fine, it's just a front end for all these tools(gogdl, legendary, WINE, etc), so something has changed in the last couple of that's causing this error

constitutional-coral•12/14/25, 4:00 PM

im having the same issue, running gentoo w/ zen kernel 6.17.8

brilliant-lime•12/14/25, 4:00 PM

Ok, finally managed to get to my PC using Pop_OS 24.04 and I'm getting the same error but only for non native Linux games

clean-aquamarine•12/14/25, 4:00 PM

The game runs through Steam without problems btw.

full-green•12/14/25, 4:01 PM

I am getting the same error in the Heroic log for a couple of different operations by the way...

brilliant-lime•12/14/25, 4:01 PM

Enter The Gungeon works just fine but Abzu just refuses to launch and spits out the same error

clean-aquamarine•12/14/25, 4:01 PM

BG3 (non-native, DX11) works btw. So it's not universal for non-native games.

constitutional-coral•12/14/25, 4:01 PM

i tried death stranding (not director's cut) and it didnt work

then-purple•12/14/25, 4:02 PM

I just upgrade my Fedora from 42->43 and I'm getting exactly the same error. Any game

brilliant-lime•12/14/25, 4:03 PM

Ok, I think I found a fix

brilliant-lime•12/14/25, 4:04 PM

For some reason disconnecting my computer from WiFi seems to allow games to launch

standard-azure•12/14/25, 4:04 PM

Works xD

full-green•12/14/25, 4:04 PM

I don't have Wifi

brilliant-lime•12/14/25, 4:04 PM

Obviously not a permanent fix, but a fix nonetheless

standard-azure•12/14/25, 4:04 PM

Turn off the internet

Ffull-green I don't have Wifi 🤣

brilliant-lime•12/14/25, 4:05 PM

If you use ethernet you just unplug it

brilliant-lime•12/14/25, 4:05 PM

Or just turn off networking in the applet that your DE uses

opposite-copper•12/14/25, 4:05 PM

You could try to add the game to steam and launch from there.

brilliant-lime•12/14/25, 4:05 PM

That wouldn't cahnge anything

full-green•12/14/25, 4:05 PM

I think I'm gonna wait for the root cause to be fixed.

brilliant-lime•12/14/25, 4:05 PM

Adding a Heroic game into Steam just adds a launch option that makes heroic invisible

CommandMC•12/14/25, 4:05 PM

Disabling umu should work for now, the issue is on their side. We can't really fix it

Oopposite-copper You could try to add the game to steam and launch from there.

brilliant-lime•12/14/25, 4:06 PM

I tried that and it didn't work with Silent Hill F

inner-olive•12/14/25, 4:06 PM

how to disable?

Iinner-olive how to disable?

brilliant-lime•12/14/25, 4:06 PM

clean-aquamarine•12/14/25, 4:06 PM

Disabling umu works. Go to the options for the game and just tick "disable umu"

CommandMC•12/14/25, 4:07 PM

Note that this is not a permanent solution, umu should ideally be enabled. I will let you know once the issue is resolved

inner-olive•12/14/25, 4:07 PM

works thanks

sacred-rose•12/14/25, 4:07 PM

Unfortunately disabling umu for Expedition 33 just causes it to error

sacred-rose•12/14/25, 4:07 PM

It does work if I turn off the internet, however

opposite-copper•12/14/25, 4:07 PM

I meant adding the actual executable of the game to steam.

sacred-rose•12/14/25, 4:08 PM

Not sure if I can get around this in the meantime

MMatt Unfortunately disabling umu for Expedition 33 just causes it to error

CommandMC•12/14/25, 4:08 PM

Yeah disabling umu is not an ideal solution, it will lead to other errors

brilliant-lime•12/14/25, 4:09 PM

Silent hill F still not working. A screen pops up for a split second which didn't happen before but then closes out

brilliant-lime•12/14/25, 4:09 PM

There should probably be a sticky post made talking about this, there are probably gonna be a ton of support threads flooding in soon
