LET'S CUT A LONG STORY SHORT:
Thank you very much for your contribution in this detailed analysis. The result is the following:
CRITICAL_PROCESS_DIED (ef) A critical system process died
Your BSOD (Blue Screen of Death) is the result of System Process Termination (SMSS.EXE is terminating due to KiPageFault exception). Smss.exe (Session Manager Subsystem) is an executable by Microsoft and running on every Windows system. Four immediate potential explanations:
- Broken disk
- Broken memory
- Corrupted files
There is no indicator that this is related to spacedesk or NVIDIA in any way. This is the first and only time ever, we see smss.exe crashing. If it was related to spacedesk, then we would have more BSOD reports like this from other users. Or we would see hints to spacedesk somewhere in the crash dump. None of the two we have. Thus it is extremely unlikely that this is related to spacedesk. Still we will keep an eye on it...
You say installing spacedesk causes the BSOD and uninstalling will fix the BSOD. Be prepared, that installing a different software might cause a similar BSOD again. We assume that this is due to disk or memory usage of additional software.
If you have any further indicators that this could be related be spacedesk, please let us know. Otherwise there is nothing more we can do about this. Except in the extremely unlikely case that we get similar reports from other users. Then we would get back to you as well.
