[2023] Paradox Launcher Doesn't Close Properly with Steam

You mean the Steam client here?

In Task manager-processes do you see stellaris.exe still in there, or components of the launcher (cpatch, dowser, bootstrapper)?

I've seen this caused by anti-virus apps in the past - What antivirus app do you use? You need to make sure all these apps are in its exceptions lists:

stellaris.exe and dowser.exe (in the Steam stellaris folder)
C:/users/{username}/AppData/Local/Programs/Paradox Interactive/launcher-v2.2023.5/paradox launcher.exe
C:/users/{username}/AppData/Local/Programs/Paradox Interactive/bootstrapper-v2.exe  

What do you see in TM then?
