Thanks for sending the spacedeskDiag.txt file.
For further analysis, could you also please send us the most recent dump files (*.dmp) of your BSOD with spacedesk which is located in C:\Windows\minidump folder.
Please save the *.dmp files in one folder then right-click the folder -> Send to -> Compressed (zipped) folder, then attach the *.zip file in your next reply.
The problem seems to be the USB driver used by the mobile phone for USB Tethering. Please check the attached dump analysis.
Can you check if there is maybe a newer version of this mobile phone USB driver and try to update?
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.
