So that little board is simply connecting all the cables from the main board into one cable (the USB C cable). If you’re getting nothing from the main board, either the board itself or the mosfet for the heater is dying.
Honestly, I don’t know how you’d go about testing board vs mosfet, if it were me I’d just replace the board, but somebody else might be able to tell you if there’s a better route to take

Yes, that little board connects many of the cables from the main board to one USB-C, the the black and the white connectors. The USB-C is the only one going to the hotend.
Anways, thank you, kind internet stranger, for trying to help me out with this. Looks like I’m gonna have to replace the mainboard.

Our hobby survives on the backbone of kind internet strangers, to deny your call is to deny yourself.
I don’t know your printer’s configuration, but assuming a pretty standard setup (single extruder, single X and Y steppers, single or dual z) I can recommend the SKR MINI 3.0. It’s a gem to handle, documentation and firmware are readily available on their GitHub, and best of all, they’re cheap and easy to source (assuming you’re in the US).
While you’re looking in to changing your main board, may I suggest you take a peek at Klipper? It’s phenomenally worth the effort it takes to set up, and you’re already going to be doing a big amount of the same legwork if you’re getting a different main board than stock.
