2019 1500 - No power to 12” Screen, AC, front doors.

I’m still having a similar issue too. U0140 codes permanently on mine showing along with every module having the lost communication with the bcm code.
At first I would get the service electronic stability control followed by No Bus and loss of window controls and AC cooling, then a blip would happen and the engine would cut off but all of the electronics would come back online.
Now it just blips with none of the previous warnings and the engine cuts off but will start back up each time so far.
I had this part 68321746AA- can buss connector replaced behind the headlight switch while at the dealership but that didn’t fix it.
Seems to cut off about every 30 minutes of drive time or so

Just a WAG, water damaged RF hub pulling down the CAN bus?

I’ll have to check as I’ve not had the rear window leak but did have the 3rd brake light leak way back in like 2019
