If that camera was on my repair bench, the first thing I'd do is take the back off and check and clean the connections between the back cover and the board.

Sitting idle for some time might have inspired a bit of corrosion and poor internal connection.

In other words, might be the buttons aren't working because the buttons aren't working

Huh? The current Seiko January 2020 catalog lists MS421R, MS621R, MS621FE, MS621T, and TS621E.

Most can be found in stock at Mouser or Digikey in the US. You can even find some of them on Amazon. Mouser shows a 7-11 week factory lead time which indicates they are still in production.
Difference between numbers on paper and reality!
Did you ever try to order them?

I did, am a regular customer of Digikey
