In some cases, when spacedesk is connected over USB tethering connection, the USB driver used by USB tethering network causes a BSOD crash.
Please try to update the Windows USB driver via Windows Update.
To verify if your BSOD is the same case, could you please send us the following for further analysis:
- 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.
