EAAntiCheat.GameServiceLauncher.exe crashing Error code: c0000409 (7)

Hi,

After updating BF6 to season 4 I started to experience crashes to the anticheat. I was able to launch game twiece (once after Windows and AMD driver update) and second one without any particular reason but I am now out of luck and it is no longer working. 

I tried to fix it with EAAntiCheat.Installer . Reinstalling, updating, deleting and checking the consistancy of the game files. I tied to delete eaanticheat files from several directories (thinking that there may be some collisions), edited the access level for this executable to read only.

I uninstalled my graphics card driver and installed fresh once. And at the end I reinstalled whole game. 

Nothing helped and as I dont have tools and idea what could I do more about it (I tried to use procmon, but it wasnt helpful) I write this post here.

Could you help me?
