Bridge 2025 Hangs When Starting

When I start Bridge it takes at least 30 seconds before anything appears in the program - all of the side panels and main content panel are totally empty. When I click anywhere on the program during this time, the title bar changes to "Bridge (Not Responding)" and the cursor just spins - clicking anywhere again just turns the display light grey and produces a pop-up with 2 options - "close the program" or "wait for program to respond".

This occurs whether Bridge opens in a totally empty folder or one containing over 500 RAW photos.

My first thought was that the Bridge cache was either full or exceeded the allocated size, but compacting the cache, purging 100% previews in cache and purging all local cache files doesn't affect this behaviour.

When Bridge is starting, the Windows Task Manager shows Bridge using 0% cpu, no disk activity, and program not responding.

I always keep Bridge up to date, so has affected previous versions during the past 2-3 months but has now become annoying.

I have Adobe Bridge version 15.0.4.534 and Windows 10 22H2, Ryzen 7 cpu, 32Gb RAM and plenty of free disk space.

Any suggestions to fix this welcomed, apart from the nuclear option of deleting and reinstalling all of my Adobe programs.

Thanks
