Hi @el_viejo,
For further analysis, could you please send us the error traces of the spacedesk Windows 10 Viewer upon app crash.
Please follow the steps below:
– download the DebugView app here: https://docs.microsoft.com/en-us/sysinternals/downloads/debugview
– extract the DebugView.zip and run the DbgView.exe as „Administrator“
– make sure to check the Capture -> Capture Win32
– open the spacedesk Windows 10 Viewer app then try to connect and wait for the crash to happen
– there should be some „SA [xxxx:xxxx]…“ traces printed in the DebugView screen, save it and send it to us
Please also monitor the CPU, Memory and Network usage (if it’s high or low) in the task manager right before the crash, then let us know your observation.
