Revit 2021 is Unresponsive

[lshannonEQEBT]

I have been having this issue where after a little while, the whole interface becomes unresponsive. I can move my mouse around and the model in the view, but I end up not being able to do any command. Left-clicking on buttons and menus highlights them and clicks them, however the commands do not register a response. It is so bad that I cannot even exit from the program, either by clicking on the "x" in the top right or "Exit Revit" in the File menu. I have to force close it with the Task Manager. The scariest part is that it will not let me save either. What could be causing this?

This is a good idea. I will have to see if my IT team can do it since we install with network packages.
