My tech support guy deleted Docker.raw. Now it won't run fix fonts (Callas). Now what?

See title. I was almost out of memory, tech support guy is rooting through stuff, I explained I use the app for work projects (it's part of our accessibility remediation in concert with PDFix), he deletes anyway. I deleted the app, I rebooted, I reinstalled, I deleted the app again, I deleted the library files, I reinstalled the app, I deleted the new install, I reinstalled again, I made sure the library files were gone, I emptied the trash and I still get this error message.

Action Fix Fonts (Callas) failed with exit code 125

I feel like I've taken all the steps advised by people in this sub and on other forums. I'm at a loss. Does anyone have advice they can offer? Thanks.
