Im not good at this stuff but pumping my kernel panics through chatgpt keeps telling me something about the memory buffer being near maxed out and webkit crashing the pc first stopping the network and then the whole system freezes happens on both versions of Mac OS I used and I used both kexts Itwlm and Airportitlwm

Here is my kernel panic
