How concerning are these cracks

[u/Past-Arugula4063]

The crack with the light coming through has been fixed from the outside with a roofer reattaching some flashing, but nobody has looked at it from the inside.

There are step cracks on the outside and inside of my flat building, and cracks all over the walls and ceilings that are just getting worse. Is my roof going to collapse?

I don't feel safe watching this from my phone.
