Paradox Launcher infinite loading and then it crashesh (Linux, Pop Os)

You'd need to remove all these folders:

• ~/.paradoxlauncher
• ~/.local/share/Paradox Interactive/launcher-v2
• ~/.local/share/Paradox Interactive/launcherpath

If that still doesn't help, the log files please:

• $XDG_DATA_HOME/Paradox Interactive/launcher-v2/logs/ (if $XDG_DATA_HOME is set)
• ~/.local/share/Paradox Interactive/launcher-v2/logs/ (if $XDG_DATA_HOME is not set)

Hajky said: it does it for HOI4 as well

Naturally, as both games use the same installation of the same launcher.
