Rise of the Tomb Raider not running on Gaming Mode

Hello guys. I just got a Steam Deck LCD and I'm completely new to both Steam OS and Linux in general so bear with me please. Here's the log: https://0x0.st/K2Nk.log I installed RotTR from Epic Games through Heroic Games Launcher, and then added the game to Steam to be able to run it in Gaming Mode, but after I try to run it it just shows the loading screen and won't show anything else. On Desktop Mode it runs fine. I don't know if I'm doing something wrong but it just won't run in Gaming Mode and I haven't found (or understood) a thread in here related to my problem. Can anyone help me?

thank you so much, it worked instantly! May I know what's UMU and why disabling it causes this?

umu auto installs dependencies many games require to run, as well as provide a runtime for proton, turning it off means you dont get any of that basically, dont turn it off unless you have an explicit reason to

^^ and even in the case that you have an issue with it, you should ask about that issue instead of just turning umu off

I don't even remember turning it off, or maybe I did accidentally while scrolling through the options but oh well. Thank you so much guys!
