❔ Am I doing event subscription correctly?
I have 2 singleton classes
SingletonA, working mostly alone and has events
and the other, SingletonB can also work alone but in my code, needs to rely on the A's events so that it functions.
both are initialized at the same time, both are uninitialized at the same time
on initialization, SingletonB subscribes to SingletonA
and on uninitialization SingletonB unsubscribes to SingletonA
but there are times when SingletonA unitializes first so the Instance reference is set to null leaving SingletonB's uninitialization throwing an exception.
do I just slap a null condition before unsubscribing or is there a better way?

also there's another singleton class that gets initialized late but doesn't rely on any classes as well, but singletonB relies on it to make some of its function work as well, what's a graceful way to subscribe to the events of singletonC if it has initialized
technically there are a bunch of things you can do, but the point is what makes sense
i imagine there should be an "uninitializing" condition that these objects should be aware of
