Cannot run virt-manager

[SameExpert]

virt-manager is giving the following error when launched from terminal:

Traceback (most recent call last):
File "/usr/lib/python3.9/site-packages/gi/importer.py", line 137, in load_module
introspection_module = get_introspection_module(namespace)
File "/usr/lib/python3.9/site-packages/gi/module.py", line 257, in get_introspection_module

repository.require(namespace, version)
gi.RepositoryError: Typelib file for namespace 'Atk', version '1.0' not found

During handling of the above exception, another exception occurred:

PS: The application is as it came pre-installed in the KDE Dr460nized Gaming Edition, nothing else installed on top of it.

I can't reproduce this on my own installation
Anyway it looks like something is missing. Is this installed on yours?

extra/atk 2.36.0-1 [installed]
Interface definitions of accessibility infrastructure

Yes, atk is installed.
