Hi guys,
Quite amazed about how many issues with 10.5 already reported. I have one myself.
I updated from 10 to 10.5 and I noticed when I left my studio for a couple of minutes, Cubase crashed out of nothing. I come back to the computer and Cubase was crashed. In Event Viewer i see the following errors:
Faulting application name: Cubase10.5.exe, version: 10.5.0.68, time stamp: 0x5da4e875

I have a Windows 10 Pro computer running Cubase Pro 10.5 with a Steinberg UR824. Windows 10 is version: 1903 build 18362.476
Do you have any idea what happens here?
