Symptoms

When running Rust, it will either not try or will get stuck half way with installing DirectX 11

Reproduction

I am not sure how to reproduce this. It seems to possibly be specific to my system.

Rust worked on Proton 5.13-6 three months ago but for Linux gamers only 6.3-4 works now and that won't install Dx11 for me.

I have:

• tried reinstalling Steam, including deleting my /.steam folder.
• re-installed Proton 6.3-4 using Steam Tools.
• re-installed Rust multiple times.
• installing the game and Proton on my boot NVME instead of the ZFS RAID.
• tried deleting just the /pfx folder
• used WINEPREFIX="../pfx" winetricks to install DirectX 11 manually.
• removing just the "HasRunKey" from the user.reg file.

Hello @EscapedAI, we're using one issue report per unofficially supported game title, so I've gone ahead and transferred this issue report to #3104 (comment).
