2nd time this week I've seen this...???
Have you installed anything else on your system recently? ie Final Cut??
Try the the fonts attached:
Helvetica & Futura
quit catalyst
just double click fonts to install...
might need a restart?
For best performance it is usually recommended to use a clean install of MacOS with no other software and minimal drivers.
If you want to use your mac for 'daily' use - might be best to create a 2nd partition or install a new HD with clean install for catalyst.
