When I remote into my Windows 10 machine, if I turn the "Show black screen" option on first and then try and log in, I receive an error:
Unhandled exception at 0x00379459 in TeamViewer.exe: 0xC000041D: an unhandled exception was encountered during a user callback.
If I log in first, then turn on Show black screen, no issues at all.
I've replicated it at least a dozen times and from two separate computers.
