Need help from electrician gods

UPDATE: I found the problem to be no neutral wire on BOX2. I don't know why that is, what are my options?

I was trying to install the Costco 3 smart switch deal in my master bedroom and having major trouble. I thought I found the right wires but they are not exactly like the diagram. I’m also getting weird readings on multimeter.
First Box:
Originally 2 whites and 2 copper grounds were capped separately. 2black and 1red going into the light switch. I know one of the blacks is a hot because it went into the COMMON, and the 2 travelers went to the other 2 spots. When I try to find the hot wire, wasn’t getting 120V on any of the red and black. I could only get 120V if I test a ground and neutral wire together, weird??
Second Box:
No 120V anywhere. The ground wire was capped on its own, the red/black/white was into the light switch, black was a COMMON

I tried many different combinations to get them to work. I know the light switch has to be on the second box, and the smart dimmer on the first. If I turn on the breaker of the bedroom plugs (separate from the light switch breaker), I get 10V on the neutral for some reason. Almost like the light switch is tied to the outlet plugs somehow?
Thanks

Answered my own question, damn electricians didn't wire a neutral wire to the other switch
Guess I'll have to use the smart bulbs instead
