I am having the same issue, going to the dealer on Monday.  Did you figure this out?

I had the same issue. Car would start and dash lit up - but no indication on spedo, rpm, fuel, turn signals, etc, etc. 

 

I disconnected the positive connection on the battery and also released the fuse lever (my 2019 Suburban LT looked different), as mentioned above. Left it over night and reconnected the battery positive, engaged the fuse lever, and boom - good to go!

 

my feeling is a passenger iphone cord caused some kind of short and the system needed a reset.
