Random crash MacOS session (hard logout/logoff)
Hello Community,
my Mac randomly log me hard off. 1-3 times a day I get for 1 second a gray display and after that I see the loginscreen. When I log in, all apps start new and it work for a half day fine.
In the system.log is every time the same:
May 11 10:42:17 rml067 com.apple.xpc.launchd[1] (com.apple.WindowServer[78318]): Service exited due to SIGSEGV | sent by exc handler[78318]
May 11 10:42:17 rml067 com.apple.xpc.launchd[1] (com.apple.ViewBridgeAuxiliary[79983]): Service exited with abnormal code: 2
May 11 10:42:17 rml067 sessionlogoutd[79981]: DEAD_PROCESS: 78312 console
The wifi.log, fsck_apfs.log and fsck_apfs_error.og is clear at this timestamps.
There are much PerfPowerServices Crash reports on the whole day, but there is only on one day a Crashreport in the Console at this timestamps:
Process: WindowServer [95142]

With an old research I found a link to a Phyton-Problem using Python 3.7.4. But I don't find the article anymore and I don't know which of my apps is based on Phyton...
Anyone a hint for me at wich point I have to beginn to search? Does anyone know something about the SkyLight.framework?
Greetings
