Screenshots fail after upgrade from Sonoma to Sequoia 15.1 plus other related issues on MBP M1

I just upgraded my OS from Sonoma to Sequoia a couple days ago, now I'm getting screenshot failures. I normally take my screenshots via the Shift+Command+4 key combination to select a certain area of the screen. I use this function a lot. I noticed after the upgrade that when I do it, I still hear the double beep sound that I normally get but there's no screenshot. I have them set to appear on my desktop, been doing it this way for years.

If I reboot, it will work but only for a short while, like for two to four times then it fails again. I've gone into Safe mode, took a few screenshots that worked, then booted back to normal mode and the screenshots worked but only for a few times before failing.

I am now reading that many have had issues with screenshots after the move to Sequoia but most seemed to be before 15.1, which at this writing is the latest.

Other issues I notice once the screenshot fails is I cannot open the Trash, it just ignores the mouse click, I cannot open About via the drop down menu from the Apple logo and when opening Force Quit, I see Finder labeled as unresponsive. When force closing Finder, it never restarts without a complete reboot.

Any suggestions on what I can do while waiting on Apple to fix this?
