Zorin Appearance not working

[Nomad1]

I can't use appearance, it doesn't save changes, also some of my apps can't open. After recent upgrade.

I'm using zorin core

zorin-appearance --version

Have you installed another python recently?

If you have the Pro version of Zorin 16, try;

sudo apt install --reinstall zorin-os-desktop-pro

for core:

sudo apt install --reinstall zorin-os-desktop

Thanks,
I've done this already with no results.

Have you been allowing the system upgrades?

sudo apt update && sudo apt dist-upgrade

[Nomad1]

Thanks for replying,
this is one of the first commands i ran.

[Aravisian]

Certainly, but when was it last ran?
Have you accepted updates from the Update Notifier prompts?

I also mentioned the same issue before

So you are telling its a python issue
but also after changing the python version to default 3.8 by
sudo update-alternatives --config python3
didnt solve the issue
