Ever since EAC was introduced, the situation where EAC occasionally generated an unexpected error when starting VRChat, and then the PC itself was restarted with a blue screen has continued for a long time. This has been going on since the EAC was introduced, and I've been waiting for quite a long time to think that some countermeasures will be taken as an operation, but since no countermeasures have been taken, I decided to post it here this time.

This does not improve at all when dealing with errors when EAC is introduced by the VRC official (for example, “EasyAntiCheat_EOS_Setup.exe” is executed. In this environment, even if this is executed with administrator authority, nothing happens and the window disappears), and although many other countermeasures were performed on the internet, this error continues to appear.

After testing treatment methods by volunteers, etc., it was determined that when there was an update in the EAC when VRC was started, it was determined that the EAC timed out while processing the update was being performed, and an error occurred in the PC. Since it is not realistic to uninstall and update VRC every time it is started, I would like you to present some countermeasures that are different from “previous” countermeasures in response to this, or improve bugs around the EAC, or the EAC specifications themselves.

Repeated blue screens on PCs can also have a huge adverse effect, so I'm expecting some kind of treatment.

Ever since EAC was attempted, I have been getting an unexpected error “KERNEL_SECURITY_CHECK_FAILURE” from EAC when starting VRChat, supposing the PC to reboot with a blue screen. This has been going on ever since the introduction of the EAC and we have been waiting for quite a long time for the management to do something about it, but nothing has been done so we thought Post it here.

I HAVE ACHIEVED THE COUNTERMEASURE BY THE VRC SIDE, BUT IN MY ENVIRONMENT, IF I RUN IT WITH ADMINISTRATOR PRIVILEGES, NOTHING WILL HAPPEN AND THE WINDOW DESTINATIONS. I have discovered various other solutions found on the internet, but this error keeps worrying.

When trying various solutions, I came to the conclusion that if there is an EAC update at the time of VRC startup, EAC may arrived that it timed out during the update process and an error may suggestions on the PC since it is not practical to uninstall and update the software every time VRC is started We would like to ask for a different countermeasure than the “existing one” or an IMPROVEMENTS TO THE EAC BUG OR THE EAC SPECIFICATIONS.

Strongly Blue Screens are very difficult to the PC, so please do something about it.
