Actual results:
Nothing is displayed and nothing can be chosen as background

Additional info:
This has been addressed in other ports:

https://salsa.debian.org/cinnamon-team/cinnamon/-/commit/6172cacec9d5012ad056606406ebbf73e3ae1a35

The workaround found in the patch is to edit:
/usr/share/cinnamon/cinnamon-settings-users/cinnamon-settings-users.py
/usr/share/cinnamon/cinnamon-settings/bin/imtools.py
/usr/share/cinnamon/cinnamon-settings/modules/cs_backgrounds.py
/usr/share/cinnamon/cinnamon-settings/modules/cs_user.py

and change instances of Image.ANTIALIAS to Image.LANCZOS

This works and the problem is solved in my case.
