Please try this:

- exit the Steam app completely
- uninstall Paradox Launcher v2 from the Windows "Apps and features" utility, if still present.

Delete the following folders if still present:
- C:/users//AppData/Local/Programs/Paradox Interactive/
- C:/users//AppData/Local/Paradox Interactive/
- C:/users//AppData/Roaming/Paradox Interactive/launcher-v2/

- run steam.exe as the Windows Admin user
- run Stellaris from the Steam PLAY button

I hope that works for you!

If not though, try running stellaris.exe directly. Does that at least get you into the game itself?
