SourceTree can no longer connect to BitBucket

[Kathleen Wilber]

On July 4, I pushed local changes up to BitBucket, as I had been doing for well over a year.

Today July 8, I tried to push changes, and get an error that I need to create an app password.

What changed?   I'll add that I tried doing that, but that password did not work, either.

Literally the same problem. I hope this gets answered soon.

What is really annoying is that if I use a different PC, install SourceTree, and clone the repository from the web into SouceTree using the button to do that, it authorizes the account properly and works.  It's only the existing version of SourceTree, on the computer I actually use for development of that code, that it has broken.  Both are the same version of SourceTree, the latest.

Is there a way to re-authorize a BitBucket account into SourceTree without deleting local files and starting over?
