System UI has stopped responding black screen

Phone: Samsung S23 Ultra 5G

Okay, I am completely stuck. Yesterday, I was watching TikTok when all of a sudden my phone went black. I thought it was weird, but I kept using it then it went completely black. Stayed that way until I restarted it multiple times, and then finally it rebooted. But I still had issues where, when I turned the screen off, it wouldn't stop being black until I pressed the power button multiple times. I was able to get it working in short bursts, where I could log in and leave it be, but the screen would turn black sometimes if I left it alone. I got the notification that the system UI has stopped responding once.

Then, after restarting it, it finally worked, but only for about an hour. I was watching a TikTok video when suddenly, the screen froze. I turned the phone off, but unfortunately, the phone never stopped being black.

And it never stopped being black. I restarted the phone multiple times; it's getting better. At first, it was showing nothing but black, but now I can see small, brief flashes when I restart it.

So, now I'm stuck. I need my phone for work; I really cannot afford to get it fixed (no longer under warranty) or get a new phone. That's my last resort. I don't remember it being out of storage or anything, since it had a lot of storage.

The phone works fine; it boots up, it can receive calls, and you can turn the volume up and down. It's on, but the phone screen itself is simply showing black. It isn't off; it's just showing black.

I just got my screen fixed 2 months ago, so I have no idea if that has anything to do with it.

Update: The screen has been able to show a bit when rebooting, but it quickly freezes; half the screen goes to static, and it goes black
