In our case, ConnectWise Control 21.3.2160.7699, Windows 10 Professional 10.0.19042.804, NVIDIA GeForce GT 1030, 32 GBs of RAM, 256 GB SSD, and 32 TBs of platter drive space. The "gray screen" on the "console" session goes away only when a monitor is hooked up to the computer. If it runs headless, the issue happens again.

Yes....this is a pretty big issue for us, too. Unfortunately, I remember this same thing happening to another version of ScreenConnect before, so you would think that the fix would be rather quick since they figured out the bug in that version, too.
