Bridge Photo Downloader Will Not Open

Bridge Photo Downloader Will Not Open

I am running Adbobe Bride 2020 on a Windows 10 PC.

Everything was working fine until unfortunately I experienced a power outage when I was using Bridge,

Now I find everything I use in Bridge appears to work as normal (at least everthing I have tried) except for the Photo Downloader which simply will not open when I click on its camera icon.

If I find its executable file in Program Files and run it from there, it opens just fine but it will not open from Bridge itself.  Something clearly got corrupted during the power cut so can anyone suggest what to do to effect a cure short of reinstalling Bridge?
