Every game crashes on boot if eGPU is connected

• Steam client version (build number or date):

• OS - XFCE Manjaro :

Description

Upon launching most games with a connected eGPU, the game will crash on boot. This includes Fractured Space, Empyrion Galactic Survival, Elite Dangerous and many others. The only one that does not crash is Stellaris for some reason. I have attached my stack trace. Compatibility options do not seem to make a difference which leads me to believe it's a driver issue of some sort. Python applications and 3D modeling applications are able to use the eGPU just fine, so it's not an issue with the GPU itself.

Thanks!

Steps for reproducing this issue:

1. Connect eGPU
2. Launch Steam
3. Run Fractured Space
4. Crash before windows can appear
5. ???
6. Profit?

Start with the attached Stack Trace and System Info, then follow the listed reproduction steps with the eGPU connected and Fractured Space installed. No source file, entry point, or test is named in the issue; done would require identifying the Proton-side cause and demonstrating that affected games no longer crash at boot in this setup.
