@FamousPig Thank you for reporting this regression, and thank you for the link to the community forum page! Both were very helpful :) I was able to easily reproduce what you described and we are taking a look.
Since the Proton updates yesterday everything now works as expected (including leaderboards and cloud save) on Proton Hotfix and Experimental. Don't know if It's something you did to target this specifically, but thanks for looking into this regardless.

Compatibility Report
System Information
I confirm:
steam-3131680-Proton8.log
proton9log.zip (It's 1GB just so you know)
Symptoms
When trying to run the game with Proton 9, the game freezes after the splash screen and quickly fills up my 32GB of memory and eventually hangs my system unless killed. Unless logging is enabled, in which case it just freezes but doesn't noticably increase ram usage. This means the proton 9 log above is created without the increased memory usage.
Using Proton 8, the game runs fine. However steam leaderboards and my cloud save (from running the game on windows) are not available. Game logs show this:
