RDP to Windows 7/8.1/10 - "An Internal Error Has Occurred" or Black Screen Upon Connection

I've had this error pop up from time to time. Most of the time turning off Persistent Bitmap Caching fixes the problem.

It can also fix the problem where you initiate an RDP connection but are presented with a black screen but a fully functional RDP session (confirmed if you use an RMM tool/VNC on the server to shadow the RDP session).

Or for those of you who like to edit saved .RDP files in Notepad:
