Easy Anti-Cheat driver blocked by core isolation function of windows defender

[mik1101]

In early May, some games with the Easy Anti Cheat system stopped running and gave an error with the code 30005, "StartService EasyAntiCheat_EOSSys faild with 1275)". Windows Defender was the culprit. It identified the EasyAntiCheat_EOSSys driver as obsolete and blocked it from running in order to preserve the isolation of the system's kernel. Surprisingly, the problem affected only some of the games, for example, WarThader was successfully launched with anti-cheat. And the problem in non-working games was observed not only with me.

After about a week, the problem was solved for all games except the Rage MP client, which still has the problem to this day. Standard reinstallation procedures, restarts do not help. EasyAntiCheat_EOS_Setup.exe from the folder with Rage MP for manual recovery does not start. I contacted Easy Anti-Cheat support and got no response.

Tell me, please, are there any other options to solve the problem without disabling the core isolation function of windows defender?
