I'm experiencing the same issue. It started happening after the update to 132.0 64-bit on Win 11. Running 132.01 now and the issue persists. (Android updated to 132.0 about a week earlier but no such issues occurred).
In my case the prompt to enter the master password appears some time after deleting the browser data of a specific website via the padlock button in the address bar. This happens on websites with a login some time after logging out and deleting the site data. Not sure about other websites, but the odd non-login website, which identifies me through a hash in the URL, seems to be affected as well. There is a delay of a few minutes and then the prompt pops up.
The master password should only be requested at the start of the session and when viewing or changing a stored password. Some settings must have been modified; however, this change is not not reflected in the FAQ or browser settings.
