Font missing randomly in certain documents - Indesign 2020 15.1.1.
I have worked on many documents and never had any issues with the two fonts I use; Open Sans and Helvetica Neue. However, recently an error have started to occur with Helvetica Neue.
In some files (not all) I can not work any longer because all of a sudden it says the font (Helvetica Neue) is missing. Find/replace font does not work even though Helvetica Neue is in that list and I can select it.
When I reopen Indesign and the file, I can quickly do something and export, and then it's missing again.
This is very annoying, mostly because I have been working for 3 years with these fonts and never had issues (and all of our documents are in the same style/branding, so I would like to keep using this font.) But I'm out of ideas what to do. I tried reinstall the font, tried multiple versions of the font as well.
