I've tried the forums but this issue is still not solved & I've not been able to find a solution anywhere. Allow me to clarify.

Thi issueeffects both the font menus and fonts in the entire document & actually across unlimited documents after unlimited numbers of app restarts and system restarts. I assume this can be fixed because I have proper behavior on one machine & improper behavior on another.

I build fonts. I use Illustrator as one of many apps in which I test the fonts as part of my workflow. The problem I am having is that fonts DO NOT UPDATE in Illustrator after I have deleted the old, installed copy & installed an updated version. If I change some characters or kerning or font names or any other characteristic of the font & reinstall Illustrator still shows me the old version of the font. The changes are not reflected in the doc or in the menus no matter how many times I start a whole new doc or restart Illustrator or restart the system.

Again I want to make clear that on my other machine which has the exact same OS & the exact same version of Illustrator the behavior is totally different. That machine behaves the same as every other version of Illustrator I've had on every machine since the 90's. If I update an installed font file the changes show up immediately in any open doc with no need to quit, make a new doc or restart. Illustrator picks up the new copy of the font immediately with no action on my part.

I can not get my new machine to behave this way after trying many, many fixes & investing many hours of research into the issue. I would appreciate some help from an Adobe expert please.
