Based on the venting of the top tank, I'd guess the bottom tank lost pressure and the top was venting to equalize the pressure differential between the two of them. They share a bulkhead, and a loss of pressure in one compromises the other. Mixing the two fuels in an uncontrolled manner is not generally desirable.
I'll be curious to read the analyses as they come in. Hoping this was an SN4 failure, and not a failure of the GSE again; failures of the Starship prototypes help dial in on critical issues of the design, failures of the ground equipment mostly waste time.
