After reading several posts about the PSE Monterey issue, and having experienced the same issues, I have opted to leave Adobe and have installed Affinity Photo. It works seamlessly with Big Sur and Monterey. After just a brief time using/learning 'the ropes' I am glad I did. I have dumped Adobe and am happily using what is turning out to be a much better (for me anyway) program. Go to their web site and check it out.
