The new Windows version (24H2) is known to block and not allow almost all anti-cheats to load and even more if you have an Intel Raptor Lake/Refresh processor (also known to have problems), maybe it’s a binary issue, I dont know, speculations.
So, try these steps:
Step 1: Repair and Reinstall EasyAntiCheat from War Thunder folder.
Step 2: Install Epic Games from the Microsoft Store and not from the official website and then EOS
- In the Epic Games client, go to the settings and find the option to install Epic Games Online Services (EOS). (That worked for me)
1. Optional: Roll back to previous Windows version (23H2).
2. Optional: Reinstall Windows from USB Flash (this is a clean reinstall).
3. Optional: Reinstall Windows from USB Flash but using other Windows .iso version like 23H2.
- Search for your .iso on the UUP Dump, and then you will need Rufus software to create the USB Flash with that .iso, if you dont know how to do it just look for a tutorial.
If that didn’t work for you and you still have the issue, search for and try other steps, or wait for Microsoft update to fix the problem.
