Short description of error
Crashes when trying to change either setting. Seems something changed between versions and you can no longer change image size or type.

Exact steps for others to reproduce the error
Run script > Go to Edit Mode > Run BFF Unwrapper > Change either setting.

Edit:

Appears to be this that causes the crash. I can run the operator twice or create image texture before hand and then changing the settings doesn't cause a crash. What changed between versions that doesn't allow this anymore?

Hi, thanks for the report. I think this is similar to #91294 (Draw: Crash on undo after adding new texture)
(Got same stack trace and also found this working on versions prior to 2b2d427bba. Will merge your report in #91294
