Hey @Mad_Butch,
Any information you could provide about these freezing would be appreciated. We have been attempting to fix as many issues as possible, but unfortunately some are hard to find (especially if you think of something working 99.99% of the time, but that means that 1/10,000 people will encounter this issue).
Also, @Theicla is correct with their description of how PlayStation 4 games break due to fault of the game. Generally, if you get a blue screen with an error code asking if you want to submit an error report, that is due to the fault of the game having a bug causing the game to crash. A system freeze on the other hand is generally a combination of faults, which can occur with a combination of factors. These include System OS faults, hardware faults (e.g. overheating), game faults, or any combination of these.
