Constant PS4 shutdowns after 5.0 update

I'm on mobile so please excuse the shitty formatting.

Ever since I downloaded the 5.0 update my PS4 has been having hard crashes. One moment I'm playing a game, and the next my PS4 is dead. When I turn the console back on it checks the system storage or rebuilds the database. Then reminds me to not unplug the PS4 power cord. It started happening at random intervals of play, but today it keeps shutting off within minutes of powering it on. Even in safe mode it'll crash.

I've tried the following things: 1) using a different outlet 2) using a different AC cord 3) redownloading the update 4) rebuilding the database 5) initializing the console 6) reinstalling the system software

I'm at a loss on what to do, and I can't buy another PS4. Please help!

Edit: why the downvotes? :( I'm desperate
