This is happening to me too and it is incredibly frustrating! Happened for the first time this morning using InDesign CC 2020. I installed and began using the 2020 version last week without issue. However this morning after pasting some text and moving it around with the arrow keys, I hit ctrl + z to undo and it went way back in changes I have made in my document. I then remade the changes and saved my document so I would not lose that bit of work if it happened again. This did happen again so I closed and reopened my document to find apparently I did not save it at that stage (?? sure I did save it ??) and lost that work yet again.
This is a huge problem, using ctrl + z to undo is an action that I do without thinking and I am sure that is the same for a petty much everyone else that uses the program!
