This issue occurs on my Lenovo B590 laptop running Windows 10, with Steam and Stellaris both installed on drive F: (my second drive); reinstalling Stellaris to C: did nothing to resolve the issue.
After installation trying to run Stellaris via Steam does nothing: the game "launches" for half a minute with nothing visible happening (at first launch the launcher got installed automatically). After that time the game closes, enabling one to "start" it again with no effect. It is possible to launch the game manually by running the .exe.
If, instead, I try to run the launcher that got installed to my laptop, it behaves as an outside launcher. That is, it requires installing Stellaris via it instead of Steam. The launcher does not recognise the Steam game at all (which, as I understand, makes sense code-wise).
The issue persisted despite multiple reinstalls, cleanses of launcher and/or Stellaris files and checks for issues in Windows. The default Windows Firewall is offline regarding the programs running, so it should not be affecting the program in any way.
While cleaning up any and all files regarding the launcher I found a lot of "AppCrash_Paradox Launcher" files in Windows Error Reporting folder. I could not access those quickly, but judging by the amount and the timing those were made whenever I tried launching the game via Steam. It tried opening the Launcher, failed and sent the error message to the WER. Since there was no visible error visual I never would have found those if not for the cleaning.
