115 Missing Font errors

I understand that many font problem have been solved in the latest pre-release version, 21.4. More here: InDesign Not Recognizing Calibri After Windows Update | Community

Where did you get your copy of the Segoe font? From Adobe Fonts? From Google Fonts? From third-party vendor?

I ask because the font is easily available from a number of sources, and your issue may not be that you don’t have the font, so much that you have multiple instances of the font, and that it’s causing conflicts when InDesign is trying to determine which instance you’re using.

Some other general questions:

1. Are you using InDesign on a Mac or a Windows PC system?
2. I have to ask: do you have Adobe Fonts activated on your system?

Please share the answers to these questions. It’ll help us better help you in resolving your font issues.
