Can't get the Rockstar Games Launcher to work

Hi,currently I’m getting headache trying to install RDR2 via RGL.The Launcher itself installs fine and I can launch it directly after installation. I also got RDR2 installed using the launcher. But as soon as I try to start the launcher via the Launcher.exe using the same Prefix it won’t launch.

Same for the RDR2.exe (also same prefix).

I tried several Proton and ProtonGE versions, all with the same result: setup and first launch work, afterwards nothing works anymore.

I’m on SteamOS 3.5.7.

Any ideas to fix this?

This the console output when running Steam using `steam -d`:
