Bridge 2020 Does Not Display Files on External Hard Drives

I recently upgraded to MacOS Catalina and went through the subsequent updating of Creative Cloud apps. Upon updating, Bridge 2020 worked fine. However, after rebooting, the files on my external hard drives are no longer displayed when the drive is selected. So, the external drives appear under Computer but when selected nothing appears on the Content panel. All my photographic/video work is on my external drives and can be viewed via Finder and all other apps including Lightroom, Photoshop, etc. If anyone has a fix for this, please advise.
