Issues with paradox launcher (linux)

Moved to Tech Support  

Launcher 2023.14 had a bug where it did not work on Linux. That bug is long fixed, the current version is 2024.2 . What launcher version are you on now?

Note that we do not support Proton or other emulations, just native Linux.

And Steam must be their native client as seen here
