InDesign is crashing every time I try to start it on my desktop machine. Computer is running current InDesign and current Windows OS.

The InDesign start screen appears, and the progress text proceeds to "Loading Shortcuts," and then does not progress further. After 3-4 minutes, the entire UI of the OS freezes, crashes, and will not restart. I have to restart the computer by holding down the power button.

I've tried uninstalling and reinstalling InDesign, but that did not change the behavior.

I am completely unable to use InDesign on my main workstation.

Help!
