Paradox launcher don't work

[ForgotGolgorot]

launcher doesn't work. When I open the game on Steam, the “launch” message appears, after which everything closes and the “play” button lights up again. The problem is with the launcher, because the games launch. I tried completely deleting all folders with the launcher, deleting the launcher completely and installing it again, but it didn’t help. also my antivirus did not block anything

Is this with HOI4?

if so see this thread

If not though, Please try this:

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

Delete the following folders if still present:

- C:/users/{userName}/AppData/Local/Programs/Paradox Interactive/
- C:/users/{userName}/AppData/Local/Paradox Interactive/
- C:/users/{userName}/AppData/Roaming/Paradox Interactive/launcher-v2/
To see the AppData folder you'll need to enable View Hidden Items in File Explorer.

- exit the Steam app entirely
- run steam.exe as the Windows Admin user
- run the game from the PLAY button in Steam

IF that doesn't help, in this folder are some .log files:
C:/users/{userName}/AppData/Local/Paradox Interactive/launcher-v2/
Please attach them here.
