no clue if this is the right place to ask for help but here I go

So my happy self has been playing java for quite some time now. I was playing on my hardcore world two days ago. I load up the launcher today, and it has an update. update the launcher aaaand my java just disappeared. I have Two separate Microsoft accounts (previously one for windows, one for java), and neither of them show that I bought, or ever even owned Java. Funnily enough, both say I have bedrock when I only paid for it on one account.  Id really love to not have to play Bedrock, any help is greatly appreciated.
