CPU debug light is lit on motherboard

Ok. I’m at my wits end now. The CPU debug light is lit on the motherboard. I’ve replaced everything except the cooler. Can a water cooler cause the CPU debug light to come on?

I’ve replaced the CPU, motherboard, RAM, power supply and GPU. I haven’t replaced the cooler because I didn’t think that could do it. I also haven’t tried a different case.

The motherboard is

MSI MAG B660M BAZOOKA DDR4 LGA 1700 Intel B660

The CPU is

Intel Core i7-13700KF

The RAM is

CORSAIR Vengeance LPX 64GB (2 x 32GB) 288-Pin PC RAM DDR4

Edit:

Googling suggests that it might be the bios is incompatible with the 13th Gen processor. Would an incompatible bios cause the processor led to come on? The motherboard website lists the CPU in the hardware compatibility list.

Edit:

I got a different brand motherboard and the processor worked just fine. Despite advertising compatibility with the 13 Gen processor the motherboard likely required a bios update that I couldn’t do without a compatible CPU.
