When pressing the "Select and Mask" it pops up and disappears in CC 21 Ver PS 22.4.3

[nancyp49936084]

"Select and Mask" function had been working fine but not after making a selection, now when I press the "Select and Mask" it brief pops up and then disappears in the workspace.  I had this problem once before in Big Sur 11.4, however, I do not remember what I had to do to resolve the problem.  I have uninstalled Photoshop CC 21 and reinstalled, but the problem persists.  

HELP PLEASE!!!!!

Have you tried resetting the Photoshop preferences, which you can under the General tab in Photoshop prefences?

I have 32 GB of RAM and 330GB available SSD hard space AVAILABLE. I just got this problem resolved. The agent had to remote in and renamed Adobe Photoshop 2021 Pref.psp to Adobe Photoshop 2021 PrefOLD.psp on my HD Library>Preferences. Issue has been resolved completely.
