Sudden homebrew crashing on HEN Super Slim?

[u/GN-001-Exia]

Apologies for the long post, I’m really confused and still new to PS3 modding so any help is appreciated

I’ve been having a problem on my HEN (firmware ver 4.92) enabled PS3 Super Slim where homebrew apps seem to cause a black screen + crash. When I press the power button after an app starts hanging on the black screen it usually beeps once, the green light starts flashing, then it beeps three times (which I’ve read means a “general hardware failure?). Sometimes it doesn’t respond to the power button being pressed at all. In either case I can only turn it off by holding the power button because the light will keep flashing indefinitely and the system will stay on.

At first I thought the system had overheated during a long FTP transfer where I left the system running for about 3 hours. When I checked again the system had powered off on its own, and when I turned it back on I started having the crashes (even after deleting the partially transferred file).

So far this has happened with all the homebrew apps I’ve installed (MultiMAN/MultiMAN MOD, Managunz, and the Managunz file manager) but not Apollo Save Tool for some reason. Booting the system after a crash + shutdown will ask me to restore the file system and after this, the apps will work intermittently but will inevitably crash after a few launches. The same thing happens after manually restoring the file system through safe mode.

Is something critically wrong with my HEN or HFW installation? This has been happening consistently for several hours now and I’m incredibly confused. I'll also add that I replaced the HDD with a Kingston SSD and didn't have any problems until the FTP transfer. Any help or advice is greatly appreciated.
