Hey im new to this stock but can someone drop the lore on why we're down 97% 😭wtf happened

Hey can someone give a quick rundown for me of why Ucore isn't able to be traded in pre and post market? I feel like i remember being able to trade it after hours about a year ago but i could be full schizo lol. Is it a company choice to not be traded after market?
