I have the same two major issues and they just started happening today (3/30/23) after Acrobat Pro (64-bit) has worked fine for the last 6 months on a new computer with Windows 11. I first noticed an issue two days ago (3/28/23) when I would get an error saying PDF files could not be printed. I had to open the files using Microsoft Edge just to print but otherwise, everything else was working. Today, nothing is working. I uninstalled/re-installed Acrobat Pro and have the same two major issues you listed assuming I can even get Acrobat to open at all.
