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//AppData/Local/Programs/Paradox Interactive/
- C:/users//AppData/Local/Paradox Interactive/
- C:/users//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
OR
- exit the Epic app entirely
- run EpicGamesLauncher.exe as the Windows Admin user
- run the game from the Epic client

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

This error means your computer is not on good internet time, which confuses our servers. Go into the Date&Time control panel and make sure Set Time Automatically is ON. Then hit the Sync Now button.

Then run the game again, the launcher will probably update itself now.

All the best!
