Rainbow spinner each time I click Add Checkmark in Comments/Filter by Unchecked

Using Acrobat Pro DC Continuous Release Version 2022.001.20085 on a 2018 MacBook Pro Big Sur version 11.6.5.

NOTEs: I have the Comment window Filter by Unchecked. I use a Apple Trackpad (and have for many years). The documents, source and PDF is on my local drive. The PDF file sizes are small, less than 1 MB, and can be 4 - 32 pages. 

Been using the workflow for a long time without issues until lately. However, recently have a problem where each time I click the Add Checkmark to the Copy Editors comment either:

• nothing happens so I try to click the add checkmark box again, and again
• And/or
• the rainbow pinwheel appears before the comment goes away
• sometimes
• Acrobat crashes

Workflow:

1. Copy/Editor adds Comments to our PDF documents.
2. Desktop Publisher (me) goes through comments in the Comment window of Acrobat one at a time.
3.  Make change to source document.
4. Click the checkbox in Acrobat's Comment window the the comment I just took care of.
5. Move to the next comment.

This workflow which normally takes say an hour or so, is now taking all day.
