However, none of the posted solutions are working for me. I've even gone so far as to try a fresh install of the OS (MacOS 10.15.5). Any assistance in diagnosing the problem would be much appreciated. Let me know what other information I can provide.
One more update in that this fix seems to hold only temporarily and I ultimately have to go through the steps again to get my fonts back. It's a workaround for now, but would love some insight on how I could fix it permanently.
