Running the current version of PS CC on a Mac with 10.15.7. All was fine until the latest security update was applied. Now PS crashes on load every time. Other CC apps are OK. Here's the top of the error when loading, any ideas?

Same here. Same OS, same immediate crash after the update. I can install PS 2020 and it runs, but I need and teach 2021.
I spent 2 hours with Adobe Tech Support yesterday. Apparently it’s a known issue. I had to drop to 2020 as well. I think it’s related to the recent Apple security update, everything was fine until I applied it. I hope they fix it soon, I do photO restoration and depend on all those new features in 2021.
Was Adobe Tech Support specific as to what the problem was with the security update? After seeing reports around the web that Apple Security Update 2021-002 broke OpenCL, I decided to try turning off OpenCL in Photoshop, and now Photoshop 2021 works again.
If you are wondering how I was able to change a Photoshop preference when it won’t finish launching, I also found that Photoshop is able to start completely only the first time after a restart. So I restarted the Mac, which allowed me to start Photoshop once, and during that session I turned off OpenCL.
But I’m not sure if this is the real fix that works for everybody. Does this fix the problem on your Mac?
If the breaking of OpenCL by the Apple Security Update is the cause of the Photoshop crash, then the permanent fix might have to come from Apple, not Adobe. Because right now this bug is also crashing other Mac image editors that use OpenCL, such as Acorn and Retrobatch.
Alas, Photoshop doesn't launch under any circumstances, right after restart or no.
I suppose one could install 2020, change prefs, then install 2021 with the import prefs from previous versions option selected...
I just tested this method and I was able to relaunch Photoshop after closing the app, OSX 10.15.7
Thanks for the advice!
Well, I tried my own suggestion and it failed. Now, I'm hoping Apple releases an update to their update soon.
it worked yesterday and then it failed today, i think i need to roll back to an earlier version of photoshop and turn off auto-update as well.
