Give this a try; completely disconnected the negative battery terminal, wait maybe a minute then re-install.
It sounds odd I know but with all then electronics in these bikes you might just need to completely cycle power to the VCM.
This past Friday I get back from a nice 170 mile ride with no issues. I’m shuffling our cars around the driveway and hop on the bike to pull into the garage. I had my Buick fob in my pocket (indian fob in the house I use my code most the time) and it seemed like my 2019 Chieftain DH was not a fan at all of the Buick fob. I didn’t get prompted for my PIN and the fuel pump wouldn’t click on at all. Tried shutting down and back on 2 more times with same result. So I get off, scratch my head, think maybe I’ll put the Buick fob away and grab the Indians. Put the Indian fob in the dash and now power button won’t even get the Ride Command screen to turn on.
So I get my wife to help push into the garage, pop the seat off, removed the negative terminal, gave it a minute then reinstalled. And Boom, fires up no issue.
There were a couple diagnostic codes thrown but they went away after i shut it down and fired up again with the PIN.
