Stuff I’ve seem suggest you somehow have a version mismatch of markupsafe with other components? Did you recently upgrade something in your stack or use pip to update something vs. Anaconda/conda?
However, given this and jinja2 having been listed a bunch before markupsafe, the same question may hold for jinga2.

You probably should run conda list and pip list on your command line to check things. You can probably search ‘jinja2’ and ‘markupsafe’ in this forum & compare listings to get a sense of versions that match better or worse.
