Hello @frichard, thank you for your post and welcome to the forum 
I see and you another forum user here experienced the same issue.
Could you please add some more info as to what OS you’re running as well as how did the update go - in-app or by downloaded the new installer and running it?
Also, would it be possible to restart FontBase and see if the issue would still persist?
If you can, please reply here:
