This is not an Other kind of report, this is a Compatibility report, please don't use the Other template to circumvent the issue template, it's lazy, and we need all the information we ask for. For what it's work try adding LANG=en_US.UTF-8 in your launch arguments

[alosarjos]

Sorry, being a kinda regression, thought it wasn't a game report.

Tested the LANG variable but still the same.

I will update the issue then using the Game Report template.

Try with this build https://github.com/CachyOS/proton-cachyos/actions/runs/25263781211/artifacts/6766476596 , it should fix it.

I had similar problem with Arc Raiders. Can confirm now it works with the proton build from previous comment.

[alosarjos]

It's still stuck for me.
