Can't find my microsoft account or purchased game on my account

I wanted to play minecraft again after like 6 months of not playing. I also migrated from Mojang to microsoft account for minecraft long ago and suddenly it tells me my email to my microsoft account doesn't exist and I was able to create a new email.

I'm so lost, did something happen that I was suppose to do that i didn't do while i was gone? My microsoft account just vanished like it never existed.
