All of it ... it's a lot. By having every single studio trying to recreate the MCU while the MCU was dramatically expanding, we have a glut of content. And, to be fair, quite a bit of it is good! But it's ... again, it's a lot. And it's really hard to get that kind of "event" feeling for most of it that makes people want to get to the theater.
From what I understand of current intentions, Marvel/Disney seems to agree with you. Part of this is writers strike impact, but we're only supposedly getting one movie next year and and an uncertain (but probably no more than six, tops, and could be as few as four) TV shows.
Now that doesn't do anything about everyone else who's dropping superhero or superhero-adjacent content, but that's kind of the nature of media competition.
