All of my skins and anything bought in the marketplace is now gone. I have to purchase it again. 1.17.30

So the 1.17.30 update came out and couldn't wait to play. After it booted up, I was a Steve character and so I proceeded to change it. After that I noticed the new UI and it was slick. But i noticed that all of my skins were gone to just alexs' and when I went to my marketplace bought skins and content. I was shocked to see everything that I have bought was resetted and I have to purchase again! Please fix this! Edit: Also when Im in a server or in a world with my friends when we die we cant pick up their stuff we have to reload
