This is the second time it's happening, and it' driving me INSANE. I open a file I worked on just the other day, and ALL THE FONTS ARE MISSING. But I never disabled the font that I used from Adobe Fonts.
There certainly are a couple of font issues waiting for improvement from the development team.
In the meantime it sometimes helps to e.g. create a brand new file and use some text in that font (if it's still available from the font menu). The font then magically re-appears in the old file which was missing those same fonts earlier.
