Battlefield 1 and 4 not working after installation (Steam + EA App)

I’ve been trying to solve this issue for several days now with no success, and it’s becoming extremely frustrating.

I’m currently using Windows 11, and I’m not sure if that might be contributing to the problem.

When I try to launch Battlefield 4, the message “Running installation script (PunkBuster Anti-Cheat)” no longer appears, but the game now gets stuck in a constant “Preparing game” loop and never launches.

Battlefield 1 simply opens and then instantly closes.

Here’s what I’ve tried so far, without success:

- Repairing both games from the EA App and Steam.
- Reinstalling both games and the EA App.
- Changing DNS servers.
- Checked System32 and found PnkBstrA.exe is missing.
- Tried manually installing EA Anti-Cheat via EAAntiCheat.Installer.exe, but it only detects Battlefield 1 (which I don’t have installed) and doesn’t detect Battlefield 4.
- Cleared EA Desktop cache.
- Checked the Windows Event Viewer, but there are no relevant errors related to Battlefield or EA Anti-Cheat.

Additional notes:
- The “Running installation script (PunkBuster Anti-Cheat)” message no longer appears in Battlefield 4.
- Battlefield 4 is stuck in an infinite “Preparing game” loop.
- The EA Anti-Cheat installer does not detect Battlefield 4 at all.

Please, I urgently need an alternative solution since I cannot play either game.

Thanks for your help.

Additional note:
I’ve already run PBsetup to reinstall PunkBuster and I’m attaching a screenshot as proof.
