I installed indesign on my new macbook pro 14. I openend an old document, and it doesnt let me edit the text frame size without changing the font, skewing it. It acts as if the frame was a piucture. I can't edit the text in it without opening the frame (command y) nor add new frames. The same happens when creating a new document: I can't add a nnew text frame to the document.
When resizing an image frame the same thing happens : It doesnt crop it but changes the size of it. (and no, no command, shift or ctrl is pressed)
If you have a silicon (M1 chip) Mac, you should check if the OS and InDesign version work together. I think the latest updates to InDesign will work in silicon, but I'd check anyway. And in case it's the file, try exporting to .idml, preferably with a computer that doesn't have the problem if you still have access to it.
