Missing fonts that are not in use?

I am getting a “Missing fonts” message, even though I am not using any of the fonts that appear to be missing anywhere in the file.

I have tried reinstalling the font that I am using (even though it is a Google font) but it doesn’t seem to work. The font was working yesterday and has only just began to show as missing. Now I can’t edit any text because of this.

I tried manually changing the “missing fonts” to the one I need to use and this didn’t work. It does allow me to type a new text, but it won’t let me choose the “Bold” weight (or any other). It says that it has changed but it is clearly is still “Regular”.

Does anyone hav any ideas?

What font are you having problems with? Have you installed static fonts or variable fonts? Have you tried reloading a file tab or app?
