I know you have an adguard, but have you thought about ditching those and using pinhole+unbound?

But this video was after a long nasty, emotional rant on the LTT forums. Also after trying to claim compensation had been agreed between Billet labs, all while doubling down in reasons why it’d not changed the outcome of the result of the video.

Have you considered using Heroic game launcher instead. I think its good as long as you use wine fixes instead of proton ones.

Edit: looks like lutris is installed but corrupted?

What about this command in terminal.

dpkg -l | grep -i lutris

You could go down the GPU Passthrough option to a VM. If you have integrated and and another GPU you could use LookingGlass and never even have to leave the Linux instance. Single passthrough is what i use to run Gamepass as you do get some good games Day one.
