Hello.
I believe you didn't test this 100%?
This didn't really solve the issue after several testing today. but bumping flask to 2.1.0 fixed it since flask V1.X.X uses the escape module from Jinja, and what i found out over my testing and googling into release notes was however recently support for the escape module was dropped in newer versions of Jinja which means that jinja version 3.1.0 seems to be needing flask version 2.1.0 to work, since that's the only version i got jinja 3.1.0 to work with.
Solution other than bumping versions
Bumping versions is indeed the easist way, you can also import from markupsafe import escape to fix the issue as well. It's stated in jinja's release notes.

Description of the changes
As described in #71 Flask is currently trying to import 'escape' from Jinja2, which removed the escape function in 3.1.0 (released March 24, 2022).
This Pull Request locks Jinja2 to pre-3.1.0 versions to prevent this issue, and adds werkzeug 2.0.3 which is required by older versions of Jinja2.
