[2023] EU4 crashes after launch from launcher.

In the game launcher please set Display mode to Borderless.

IF that doesn't help, Please do a full **clean** re-install:

- move any valued save games elsewhere
- "uninstall" in Steam-EU4
- manually delete both the Steam/SteamApps/common/EU4 AND Documents/Paradox/EU4 folders
- re-install game in Steam, run a Steam Verify when done.
- add EU4.exe to the exceptions list of your antivirus app; ESPECIALLY if you have Windows Defender, add it to the Ransomware "Apps Allowed Through" list.
- start the game with no mods active and test

In particular make sure there are no files or folders left under either the Steam EU4 or Documents EU4 locations, before installing again.

Also if you have installed RivaTuner, RadeonPro, or a gaming VPN app called Evolve, or the MSI Gaming App, or Duet, disable it as it clashes with this game.


IF NEITHER OF THOSE HELP:
DXDIAG is a program you run from a command prompt or the Windows start menu 'run' dialog box (or 'search programs' in Windows 7 or later). After running it will open a window and start collecting info with a progress bar in the lower-left corner. When it completes click the 'save all information' button and save it to a file then attach that file here.

Please attach your Documents/Paradox/EU4/settings.txt and pdx_settings.txt .
From your Documents/Paradox/EU4/logs/ folder, attach system.log , error.log .  

We are having trouble with Avast and our new launcher 2021.1 , although not necessarily this exact issue. Add eu4.exe to the exceptions list of Avast. You should add steam.exe and C:/users//AppData/Local/Programs/Paradox Interactive/launcher-v2.2021.1/paradox launcher.exe to that list. You may need help from Avast support in how to allow those apps through fully.

The same may apply to other antivirus apps.

Let me know if that helps!  

Yes, your antivirus app has deleted or quarantined that file. Which one do you use? You may need help from their support to stop it doing that.
