Robinhood uses Apex behind the scenes too. Apex is probably having trouble clearing these trades (given how one sided it is) and just decided to not trade them, resulting in the butterfly effect of multiple brokerages not trading these stock.

That's... not how stock markets work. For every buy there must be a seller. If there are too many buyers but not enough sellers the price simply goes up.
Sure, that's what would happen if buys and sells could reasonably be paired up. Robinhood/Apex could've just kept these buy orders open until it found a seller at any price and closed unfilled orders at the end of the day. That would probably be less preferable to all involved as I doubt these people were placing limit orders.
