So all those problems are fixed but somehow new ones keep popping up?

Yes. Welcome to reality.

Maybe it wasnt real change but actually just band aids and the root cause stayed unadressed through all those years.

Somehow the system you want to maintain and support keeps creating these problems.

There are a lot of problems, and yes the solutions to old problems often create new problems, because reality is not a video game where collecting a dozen McGuffins ends the quest and you get a reward and then never worry about that issue again.

The options are:

1. Pick up the pieces and try again.
2. Give up and die where you are.
