Locally-installed plugins disappearing from Windows computers

I’ve gotten multiple reports that on some Windows computers, locally-installed UXP plugins disappear. The only solution is for the user to reinstall using the .ccx files. One person sent a screen shot of the “External” folder where the plugins are stored and it showed my plugins and others were properly in place there. However, they do not show up in the Creative Cloud Desktop app “Manage Plugins” section. Still working on trying to find a definitive solution (like repairing or reinstalling the CCD app), but at this point, I don’t think this is a one-user problem anymore. Just wanting to let others know that this problem seems to be out there for locally installed plugins. It’s not common, but it appears to be real.
