[2023] [Proton] Crashes during login after last update

There is a small Linux community here - like the knowledgeable ggg above - who I hope will be able to help with this. Unfortunately we’re not able to dedicate any resource to investigating Linux-related issues at this time.

I have recently spoken to another Linux player who had to update Steam, in addition to the OS, to resume playing after running in to networking errors. I don’t know whether this could be of any relevance to you.
