R77 crashs some process

[wineggdrop]

I find out that R77 would crash some process on windows 10+ or windows server 2016+,evenlog shows the crash with error code 0xC0000005 aka Access Violation,it only happens in some mechine but no all and the crashed process normally dllhost.exe,svchost.exe

Maybe some unlikely null pointer dereference in one of the hooks...? Do you have a process that with a reproducible crash? That way, I could remove one hook after the other until it no longer crashes and I could see which hook caused the crash - or any other component in that sense.

I may found out why.

some process with Arbitrary Code Guard or Binary Integrity Guard enabled windows 10+/windows server 2016+ doesn't fall into the low integrity catagory(some of them do fall into it),and it probably cause the crash while injected. As the crash result from event log states mostly process svchost.exe or dllhost.exe,to be sure,it may need more test on different windows version.
BTW,I labels Arbitrary Code Guard or Binary Integrity Guard enabled as Blocked

after some test,it may be the root cause of the crash.after leaving Arbitrary Code Guard or Binary Integrity Guard enable process un-injected,won't see the process crash log on eventlog after R77 installed. Tested on windows 10/11,server 2016-2025
