Launch Library 2 records it as a failure: After liftoff, the vehicle sustained fires from leaking propellant in the aft end of the Super Heavy booster, severing connection with the vehicle’s primary flight computer. This led to a loss of communications to most of the booster engines and eventually control of the vehicle.

Unexpected severe damage was also im The mission went to suborbital for SpaceX. The upper stage was Ship 24. Booster 7 flew for the 1st time, and was not recovered.
