it began in sanctuary, when I was locked into a suit of power armor that had no HUD. I was able to actually climb into a second set of power armor while stuck in the original suit, and then exit the 2nd suit as normal. the original suit was then gone, lost to the programming abyss. which was fine with me. whatever, didn't care too much.

Until i realized my pipboy was invisible, and therefore useless. I can navigate around the interface, i can tell by the sounds-but its invisible, I know that this is a common glitch, and I did everything I could to fix it, i quicksaved, loaded, waited indoors for 24 hour cycles, exited and reloaded the game, powered down the ps4 and restarted, absolutely nothing works, i just get a blurry background as if my wrist is supposed to be there displaying all this stuff and a few commands at the bottom

Equally as bad, and I have been unable to find anyone talking about this: as this started happening, I noticed I was no longer able to sprint when running around. then I noticed that in VATS, I can't use any of my full AP bar to select any targets, it just plays the sound like I don't have enough AP and i'm screwed.

The worst thing is, this seems to have crawled backward into my older saves from the night, and now they're all affected.

Getting into power armor, i can see the pipboy display and use my AP. I'm afraid that when I originally climbed into the second set of power armor and exited, it somehow, like, stripped the data for the pip-boy from my character and now its all stuck crammed into that second suit of power armor.

The most recent safe save i have is from 5 DAYS AND TWELVE LEVELS AGO. I have completed so many pain in the ass missions and done so much settlement building in the past 5 days I really don't think I can bring myself to play this game again for any amount of time if I have to redo that, i honestly will probably just sell it and get it out of my life so I can resume real life.

If anyone has any experience with this, please, please let me know what I can do.

Since it is effecting all your saves I'm guessing it's a game data issue. Try deleting the FO4 game data (NOT your save data) then reinstall the game and load up a save.
