Bridge v15 Hangs When Starting

Bridge v15 hangs for approx. 30 seconds each time it starts, whether or not the current folder contains any files or is empty. If I click on Bridge during this time, the display turns grey and I the title bar displays a "not responding" caption - further clicks cause a Windows dialog to open with options to wait for the program to respond or terminate the program.

This used to be a problem early this year but one of the spring 2025 updates cured this, until it restarted after an August 2025 update, but now it occurs every time the program starts.

I have purged all 100% previews in cache and also purged all local cache files, but this makes no difference to the delay when Bridge starts. It doesn't make any difference whether the current folder is on an internal SSD or not - I don't use Bridge with any external drives.

My PC is running the current version of Windows 11 with the latest updates and a Ryzen 7 cpu, 32Gb RAM and plenty of free disk space. All of my Adobe programs are also up to date and my Bridge is version 15.11.729.

Suggestions to fix this are welcomed.
