Thanks for your input.
It seems that your primary machine is crashing.
Is it only happening when you send an input using Apple Pencil 2 via spacedesk iOS viewer app?
For further analysis, could you please send us the following:
– run dxdiag.exe on your primary machine, click “Save All Information”, save the output file (dxdiag.txt)
– most recent dump file (*.dmp) of your BSOD with spacedesk which is located in C:\Windows\minidump folder
Please save the files in one folder then right-click it -> Send to -> Compressed (zipped) folder, then attach the *.zip file on your next reply.
