Description

I tried running the demo to Little Nightmares II using Proton but it crashes at launch with the error message "Fatal error!". The Steam AppID of the game is 1443440. I added PROTON_LOG=1 %command% to the game's launch and got the following log:

steam-1443440.log

I have checked whether there are updates for my system available and I am up to date

GPU: R9 270 2GB

Driver/LLVM version: Mesa 20.2.3/11.0.0
