@marlboro50 Wow, that's a very good call. Thank you, my system is now updated and I can settings again.

Edit: I'm confused, how do I mark this as solved?

I'm on RC update channel. Since a couple of months ago and after a system update I can no longer open the settings app. It loads for a few seconds and disappears. This also means I'm not getting any more system updates.

Any ideas how I might go about fixing this?
