There's an additional parameter some people have had to use in Monterey (12.3.1 I think) for the DW1820A: brcmfx-delay. Meaning you need to inject AirportBrcmFix kext too but I think you do.

In the following post, OP set the delay to 27s, there's a good chance it'll fix your issue too:

There is no firmware you can load on these cards except Bluetooth ones and that won't be of any help re: boot loops/freezes.
