I have a problem with FONTS in both Premiere Pro and After Effects. When there is no internet connection, and I open a project, After Effects shows me an info that fonts that I used are missing, and changes my font into another one. Such situation is very problematic for me, because there are situations that there is no internet connection in the area where I live, and I can't work - because I have no access to fonts that I need or used in the project.
So this depends on one factor (I think). Are you using fonts from Adobe Fonts? Adobe Fonts has a feature that enables fonts for you at any time but does not "install" them onto your computer. If you need these fonts, look them up on Google and install them from other websites.
