Pink Screen of Death after housing swap

I swapped the housing for a customer on an iPhone 14 pro max with an OEM/Pull housing from a well-known supplier. I have done so many times without any issues. This time I am getting a reboot with a pink screen every 2 to 3 minutes. I have the panic log, and it points to the power flex. I would like to know has anyone had this issue and is it normal for the power flex to function but, still cause panic? I have another power flex and wireless charging flex on order.

panic(cpu 1 caller 0xfffffff048921f84): SMC PANIC - ASSERT: target/d74/target.cpp:266: 0, SMC BSC failure, spreadsheet ver(*10) 150

S.sensor array 0 - 4 is 0x0, 0x100000, 0x0, 0x0, 0x0

F.sensor array 0 is 0x0

The power button flex on an "OEM" housing with small parts was causing the issue. Swapped it out and no more pink screen of death.
