Hello, I am having this same exact problem. I don’t know how to fix it besides doing a hard reset. I can say that after you hard reset your console and disconnect the ac cord from the PlayStation for a couple of minutes, then it should happen less often. This has never ever happened to me before and I have had my ps4 ever since it first came out. I’m thinking it has something to do with an update but I’m not really sure. I only say this because it’s happening to a lot of people from owning the ps4 when it originally came out, to having a new one they just bought not to long ago. Hopefully this gets fixed ASAP
