New issues with Bridge

3 years ago I moved to CC 2017 and Bridge. No problems with either during over 1000+ hours of use. Last July (2019) I built a new workstation. Installed the latest vesion of Photoshop (currently 20.0.6) and Bridge (currently 9.1.0.338). My OS is Win 10 1809 (OS build 17763.805).

During the last 3 months I have easily accumulated several hundred hours of usage. To date, Photoshop has not crashed once. Until 2 days ago the same with Bridge.

Now Bridge is unstable. It freezes or crashes. When I view images in Filmstrip they disappear within 1 minute or less. The images in Content remain (assuming that the program did not freeze or crash).

If I switch to Essentials and select an image it appears in Preview. Again for only about a minute.

These problems exist even when no other programs including Photoshop are open.

This morning I uninstalled Bridge. Shut down the computer, rebooted, and reinstalled Bridge. Same problems.

Prior to this issue which began 2 days ago no new programs or updates were installed to my computer.

What do I try next?
