PE add media Failure, Generic Error
I am a veteran PE user and am currently using 2021. I had to reinstall it so I downloaded it from my Adobe account and activated it. I then tried to create a new project and added .jpg, .png and .mp4 files to it. I immediately got import error messages: "The importer reported a generic error" or "This type of file is not supported". I'd never received this type of error message before. I tried all of the repair steps mentioned here and in Google responses to no avail. I finally did find a fix and it's pretty simple. I created a new project and changed the the project settings from AVCHD 1080p60 (which was the default) to something different (Full 1080i 30). I then loaded test media (file types mentioned above) and had no import issues at all. I tested this a few more times and then changed my settings back to the default and have had no similar issues since.
