My daemons keep crashing on Monterey beta 7 and 8 when calling selectors form NSFileManager: Fore example: attributesOfItemAtPath:error: .

Application Specific Information: Could not establish connection to coreservicesd. Err=(os/kern) successful (0x00000000), rpcResult=0, port=0x2703. (1/0/0/0) abort() called

Does anyone else experience this? Is there a macos bug on this that will be fixed with the next beta?

Also, can you post a full crash report here. See my Posting a Crash Report post for advice on how to do that.

In our case, the reason of the issue was preventing GET_TASK operation for the crashed process in Endpoint Security system extension. coreservicesd needs it in Monterey when the process calls NSFileManager's methods.

The solution was muting the coreservicesd for es_client intercepting ES_EVENT_TYPE_AUTH_GET_TASK.
