Even I'm facing the same issue while installing fonts. I use Fontbase free version, and it pretty much works fine. When i activate one of my fonts from the local repository using fontbase most of the programs (Photoshop, InDesign PremierPro) crashes. I have noticed Illustrator doesn't crash, just these three as i always use the above 4 apps. Something is term=billiy wrong.
I'm on Mac with OS Catalina 10.15.7 and all latest Adobe CC
