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.
