Is there a way to uninstall Bridge 2021 and reinstall Bridge 2018? I can't copy my jpegs to a USB

Normally I can do batch transfers in a reasonable amount of time, but not in Bridge 2021.  This is bad.  Yesterday I tried to "copy to" about 100 jpegs to a USB.  Normally,  it doesn't pretty quickly.  Yesterday, however, after 3 hours, it was still not even close to being complete.  Now I am trying smaller batches and it's not much better.  I tried to copy 20 jpegs 20 minutes ago and the job is still not complete.

 It also doesn't recognize some of my hard drives.
