Ps4 keeps crashing and freezing

So this just started about a week ago and at first it was only once in awhile but now it’s literally every game. So I will be playing a game then a message pops up and says that my game is corrupt and to delete the file and then the ps4 will spit out my disc. If I’m playing a digitally downloaded game it’ll say the same thing then just close out of the game. When the game freezes my whole PlayStation does not freeze so I am able to close out and try again but it just does the same thing again. I can watch movies and stream Netflix on it still but games just do not work anymore and was hoping someone could help me out because I really do not want to buy a new one with the ps5 being so close
