VSC extensions

Yesterday my html template stopped working.
I traced the problem to being one of my (sadly many) VSC extensions for code linting, formatting, beautifying both html, jinja, python and more. I uninstalled them all and the code now works again (in the pre-“formatted” state).

This leads me to asking you guys if you have a selection of recommended AND SAFE extension for VSC that help format both python, html and jinja automatically without introducing errors?
