Bridge 2023 crashes before I can implement remedies

Suddenly began to get Unknown System Error, on relaunch, got my last screen complete with active thumbnails/previews and all panels poplated. Clicking a thumbnail yields multiple flickering boxes. Read support document remedies, nothing special to lose so uninstalled Bridge, reinstalled from CC.

Launching new Bridge yields incompletely populated error box; on dismissing box or clicking menu item, Bridge folds-up and disappears. Repeating uninstall cycle produces same result. I'm locked-out.

Thanks for any solution a point-n-click-guy can perform without breaking-out in hives.
