Good day! I'm Raniel, a Microsoft user like you. I understand your frustration regarding this issue and I'll do my best to help.
Just to clarify, have you also tried to connect the external storage to a different PC to isolate the issue?
Kindly double-check if your machine doesn't have any pending security patches: Go to Start > Settings > Update & Security > Windows Update > Check for Updates. Also ensure that the necessary drivers for your machine are properly updated by getting them from the manufacturer's website. You may refer to this guide:

Once done, remove the external storage on your PC, then perform a clean boot: https://support.microsoft.com/help/929135/how-t...
Connect the external storage to a different USB port on your machine, then check again.
I hope this helps. Good luck!
