PS5 recently unplayable from graphics issues covering 3/4 of screen

I’m on PS5 and a since a few days ago there have been huge graphical issues that make it where i cant even see the screen. Lines and lights everywhere, even on the main menu and login screen. when im in game i literally cant see 3/4 of the screen, it’s just a huge bundle of bright lights and lines. no setting changes to the tv or ps5 or in game have helped it. Can’t find any help online so far, its just people talking about how great their graphic cards are. But game was fine until recently… i have pics on my phone but i assume people know what i mean when i say the majority of the screen is just a bright cluster of lines and circles that i literally cant see anything im doing. I’ve only seen a couple of topics about this but its no actual information as to why it worked fine and now it pretty much just doesnt work anymore.

edit- to be clear im talking about Diablo 4 on ps5. ive checked other games its just this one. If i were to upload an image, it would be a tv with most of the screen shining very bright where you cant even see anything other than a little bit in the corners. sometimes its a little less bad but still very bad, sometimes literally cant play because i cant see.

Weird.

I can only think of one thing to try and that is have the PS5 check game file integrity ( I think that is a thing, not sure though).
Failing that a D4 reinstall perhaps?
Something got corrupted sounds like if other games are working fine.
