Unable to use game mode & unable to update

Since today I have been unable to use game mode, getting the error in the second attached image when for example clicking a game (only way to continue when it occurs is to reboot). Decky Loader has the error attached in the fourth image.

I am also unable to update. First I tried the updater in the game mode settings after reaching 20% it prompts for a reboot as if it was finished, but going back to said updater just shows another update (it cycles through the same two updates (13th of May -> 15th -> 13th, etc.).

This is a stock hardware 512GB LCD model, system information attached in an image.

Solution
Uninstalling Decky Loader fixed the issue with those fullscreen errors in game mode, I'm guessing the theming engine broke something 😅
