Empty window when running on macOS Sonoma 14.4 after Firefox 124.0 Update

I have been using ff-password-exporter 1.2.0 on my Macs for several years. It's still doing fine on most of them, but on my main machine it began failing to launch after Firefox updated from 123.x to 124.0 several days ago. I've tried everything I could think of to isolate a cause, but I've come up with nothing useful. Tried deleting and reinstalling ff-password-exporter, replacing my Firefox application, and even refreshing Firefox. Nothing helped. I can use the Firefox built-in option for exporting passwords to a .csv file for the time being, but a feature I really like in ff-password-exporter is that it gives a count of times used for each login password. That's really a cool feature and makes it so easy to identify the most frequently used passwords. I hope there will be a fix. At the moment, I have no clue what's causing it on this particular Mac. Thanks.

By the way, the machine in question is a 2018 Mac mini. The application is running just fine on an M1Pro MacBook Pro and an M2Pro Mac mini. All three are on the latest version of macOS (Sonoma 14.4). Any thoughts or suggestions?
