Python Quart import error : cannot import name 'soft_unicode' from 'markupsafe'

I am installing the Quart module for Python on a newly upgraded server - to Debian 11:

name -a
Linux 9D895EB 5.10.0-19-amd64 #1 SMP Debian 5.10.149-2 (2022-10-21) x86_64 GNU/Linux

When I try running Quart I get the following:

Traceback (most recent call last):
  File "/usr/lib/python3.9/runpy.py", line 188, in _run_module_as_main
    mod_name, mod_spec, code = _get_module_details(mod_name, _Error)

ImportError: cannot import name 'soft_unicode' from 'markupsafe' (/usr/local/lib/python3.9/dist-packages/markupsafe/__init__.py)

When I installed quart on my previous dev box or laptop I didn't get this issue. I have seen comments about installing a previous version of a library, but, nothing related to quart as such.

Here is a list of installed module versions:

Jinja2             3.1.2
MarkupSafe         2.1.1
quart              0.18.3
requests           2.25.1
Werkzeug           2.2.2

Update: With the update to MarkupSafe 2.1.1 and the others I now get:

File "/usr/local/lib/python3.9/dist-packages/quart/cli.py", line 506, in _load_plugin_commands
for point in entry_points(group="quart.commands"):
TypeError: entry_points() got an unexpected keyword argument 'group'
