Save/Save as are greyed out, as well as undo and redo. Key commands don't work either.

I'm running InDesign 2022 17.01 on a Macbook Pro 2019 OS Monterey V 12.1. 

I use indesign on this computer every single day with no issues, but today, I am unable to save my projects or use undo/redo. I restarted indesign earlier to address the undo/redo problem and it worked for a while, but eventually was disabled again. At the time, I was able to save my files so I felt comfortable restarting the program. But now, both save and undo/redo are disabled. I was however able to succesfully export, which requires saving. Very strange. 

other things that may or may not be related:

- Text boxes in one of my projects are creating duplicate edges and I have to double click them for the text to readjust inside the new parameters. Usually the text adjusts while I drag the box. This is only happening on one of my projects open, while the other is normal. 

- Zooming with my fingers on my trackpad is randomly disabling and I have to relaunch the program to fix it. Zoom on trackpad works in other windows on my computer and in other Adobe Programs while this is happening. 

As I was typing this, the program went unresponsive after I attempted to package my file as a work around to not being able to save. I got a pop up that said "InDesign is shutting down. A serious error has been detected."
