Windows 10: How to fix error that programs cannot write files in my appdata directory

Hi,Since Wednesday evening 2nd April when I shut down and restarted my laptop, I have been getting error messages from various programs that cannot write files within my appdata folder. For example: There was an error while accessing the configuration file at c:/users/me/AppData/Roaming/appfolder/appdata.cfgI am also unable to open some apps from the taskbar or start menu, including Edge and Chrome. Windows is able to start Edge from a search within the start menu but judging from an error message which flashed up after using Edge in this way, I think it was running with elevated permissions

Huge Number of files in AppData\Roaming\Microsoft directory

I have a similar folder but it contains only a handful of files. You can do this to find out a little more:

1. Mark the first code line below. It extends over two lines.
2. Press Ctrl+C to copy it.
3. Click the Windows orb.
4. Press Ctrl+V to paste the code line, then press Enter.
5. You will see a screen full of files, with the most recent files on top. Make a note of some file sizes and date stamps.
6. Repeat Steps 1 . . 5 with the second code line. You will again see a file list, this time with the oldest files on top.
7. Report what you saw.
