Broken maximize button

Help

So, after some time using KDE I noticed my maximize button suddenly stopped working. I have no clue why. I restarted my PC multiple times and tried to remove and add back the maximize button through the system settings but it just does not work:

Shortcuts to maximize don’t work either. I used to have a different theme on and it would show the button but it wouldn’t do anything when clicked.

I have some tiling scripts installed like Krohnkite and Bismuth, they were never activated at the same time. Currently all scripts are disabled and I restarted multiple times without any scripts.

In ~/.config, what are the contents of kwinrc?

Particularly important is the [org.kde.kdecoration2] group, which should contain the key ButtonsOnRight if you have changed anything. If it doesn’t exist, it’s using defaults and the problem is even more bizarre. if it exists, remove it.

I found it! Super sorry for the late reply. Do I delete the whole [org.kde.kdecoration2] group or just ButtonsOnRight?

Take a backup of the config file and delete just the ButtonsOnRight then logout and back in.

Did. It didn’t work. I restarted my PC fully and it still wouldnt show the maximize button. As before the maximize button is showing on Chromium, but it still doesn’t work. What now?
