How to gain access back to my minecraft account

Question

Changed the security info towards a different email and now when i sign in to minecraft through a client it says i havent purchased the game. This has only occurred now that the 30 day period waiting period of the change has ended. I had a different Minecraft account already using that other email which only has bedrock in it and when i try signing into that account it doesn't sign me in at all. Also when i log on using my old email that ive always used, it shows my minecraft username but later then says that "No Multiplayer Access, this Microsoft Account has not purchased Minecraft"
