2019 MacBook Pro won't start after Monterey update

I've seen some talk here about MacBook pros not starting after the latest update. I'm in the same camp (2019, intel iris chip). Never had an issue before. This is an actual issue with the update correct? I've seen some talk here about Genius Bar blaming the problem on faulty hardware.

Super infuriating. Has anyone had their MacBook Pro turn back on after a while?
