This specific error can occur if you are using a newer Python3 version that deprecated certain types of imports. Easiest short term solution is to move to an older Python version (something older than 3.10).

If able to update Python packages, it may be possible to resolve this by upgrading the packages in use on your system via “pip install <package_name> --upgrade”. The most likely culprit is the Jinja2 package, but it isn’t entirely clear which package is triggering the error based on your post.
