EAanticheat problem!! game wont launch

Had the same issue but managed to install anticheat though anyway game just not launching and not showing any errors. 

when did the issue start, did u fix it?

and to add, the first time i tried to repair, Eaanticheat,  using the installer from EAs website, it showed error of gamepath not valid or something like that, though on redoing the process it showed successful, but it didnt work. Now even errors are gone...game just wont launch.  I run the WINDgb, on the game crash dump, and its output pointed to EAanticheat being the cause,  and then i fed it to Ai, it said... following

The dump shows an access violation (0xC0000005) inside EAAntiCheat.GameServiceLauncher.dll at an indirect . The instruction tried to use an invalid pointer (attempted read ) and registers contain repeating/garbage patterns (), which strongly points to memory corruption or an invalid pointer/vtable inside the EAC launcher process. In practice that pattern is most often caused by one of these: kernel driver interference, security/antivirus injection or blocking, Windows Core Isolation (Memory Integrity), overlay/injection tools, or a corrupted EAC binary.

the issue started 2 days ago - the game was launching after 8-10 tries. But today was not launching all day at all. First was saying that some problems with anticeat - after several tries was able to update anticheat while launcing. And now it says something like "problem is on our side, try to launch later".

 i have a suggestion for you, go in your windows update, history, and see if you had a update of,  Security Update (KB5074109) (26200.7623)

in recent days.  Now this may or may not be the problem. Coz fc 26 always had  a problem with Eaanticheat, even before this. But yes last two days were absolutely worst. I cant play enter the game. 
But this windows update, had many problems, so many problems,  with various softwares, and games.  that microsoft had to tell its users to undo this update. so u can try it. Me sadly am unable to do it, coz it doesnt show up in my uninstall list.  but its worth a try.
