Reporting in form Arch linux with NVIDIA GPU, seeing same issue, but core of problem seems to be between game and steam, if I launch the launcher manually with out steam game seems to comes up fine. not certain what all is missing with out or how to verify that all purchased content is working separate from steam, but I can play my local saved games.
bin/sh /home/yourusername/.paradoxlauncher/launcher-v2.2023.14/Paradox Launcher --pdxlSessionId 4000000b-0000-0000-0000-a0000000000e --pdxlGameDir /data/SteamLibrary/steamapps/common/Stellaris --gameDir /data/SteamLibrary/steamapps/common/Stellaris
the pdxlSessionId might be unique per user but the bogus one I made up here seemed to work so it might be part of the steam interactions
This seems like the best option as trying to change out CrashReporter did nto work very well, all you loose here seems to be steam interaction,
