This just started today. I am working on a Mac and using Illustrator 2023. I've closed the program and reopened it several times, checked other files I have as well and it's driving me CRAZY. I can't seem to select an object and drag to move it. The only way to select an object is to drag and draw a rectangle around the shape and even then I can't drag to move the object. Any ideas?
If your issue is happening with more than one Illustrator file, I'd suggest restoring Illustrator preferences (this will restore all your Illustrator preferences, and you'll need to set them up again).
One way to do this is to go to Preferences > General and click the Reset Preferences button at the bottom of the dialog. Click OK, and you'll be prompted to restart.
