You must have run the launcher from the desktop shortcut, which is a standalone mode for users who do not want to run Steam. EU4 was never ported to that platform.

You need to run the game from the Steam PLAY button instead, as before.

All the best!

As I said, EU4 was never ported to the standalone launcher. Does it run from the Steam PLAY button okay?

What antivirus app do you use? You need to make sure all these apps are in its exceptions lists:

eu4.exe and dowser.exe (in the Steam EU4 folder)
C:/users//AppData/Local/Programs/Paradox Interactive/launcher-v2.2022.9/paradox launcher.exe
C:/users//AppData/Local/Programs/Paradox Interactive/bootstrapper-v2.exe

IF that doesn't help, also set each of those .exe files (EXCEPT eu4.exe !) to run as the Windows Admin user.

Then the game should run from Steam/our launcher, and enable all the DLCs.
