Seems like you installed WTForms greater or equal than 3.1.0 see related issues:

• Just released WTForms 3.1.0 break FAB widgets (including just released 4.3.8) dpgaspar/Flask-AppBuilder#2137
• Limit WTForms to below 3.1.0 #34943

You need to install less then 3.1.0 (pip install "WTForms<3.1.0") or use constraints file, see: Installation from PyPI

Wow, that worked! You are amazing guys, thank you so much @Taragolis!

Wanted to add another datapoint, we are on Airflow 2.6.3 and our users/roles page has been broken for a long time, same error as above. Downgrading to WTForms 3.0.1 fixed the issue. Thanks all!
