After the Xbox loading screen I get a black screen and can’t get out of it.

Have you tried unplugging the Xbox and replugging it?

I did what you listed and I'm still getting a black screen after all the logos load

Xbox doesn’t need an update; i am on Home Screen; I can’t really load or do anything though; any actions freeze and take minutes to load games and apps or an app; can’t open anything in settings as “it takes too long to start” the xbox is horrendously slow even though i just factory reset it, and updated mind you, but everytime i turn it off i get a black screen turning it on and have to power cycle, sometimes it gets stuck on green screen but luckily for now after a few attempts i can still be brought to home screen, i just honestly can’t turn the xbox off because i don’t know if it will end up breaking again and have to factory reset it but i can’t even use the xbox as is, as everything freezes and takes forever to start or do anything, had a game download to 75% just for it to stop for some reason and i can’t pause the download or anything because it freezes and takes too long; debating opening the xbox and cleaning though it’s been cleaned before and it still eventually ends up useless; TLDR: xbox can’t be turned off or gets stuck on startup, several tries eventually show home screen but xbox is too slow to even use or do anything with

Quantum - Yes, very similar. I haven't tried clicking around to get the Signing On screen to minimize, will try that today. Mine will sit there with a Black Screen, the "Signing On" circle spinning for a minimum of 45 secs after the primary Xbox loading
screen. Then it jumps to the Home.

I feel like I get this problem too, but after 2 minutes of looking at a black screen, it finally loads.

But interesting enough, about 2 weeks ago, I moved it over to an external SSD drive and I don't get the black screens anywhere near as bad.
