Robinhood had a liquidity problem in the same way as ERCOT is having a power problem. That is, the corporate entity is Ok, and you have to deal with the problem.
I would not say Robinhood the corporate entity was okay, they seriously fucked up and could have seen this coming. Tenev called it a "five-sigma event" - lol okay. Sure it was, as if volatility blow ups happen once every 8 millennia...
