PS4 Bug Fishing at 2am

[Notriom]

I was fishing for the legendary fish, it was 2 am and I managed to catch it, but I fainted and the fish just disappeared, and I had managed to catch it

Not a bug, unfortunately. The time it takes to reel in a fish is not protected or paused, and a dropped item (such as a fish released from a hook because you passed out) right above the water vanishes into it. You can only catch it once per save file so if the PS4 allows restoring to your previous save I'd definitely recommend it, and try to not catch a fish *at* 2am.
