What is happening:

I can't access the Minecraft Marketplace and see/modify/use my skins on Switch when I start my game (look at the attached videos) My minecoins are also not loading. 

What should happen?

Before the 1.19.20 update, it was fine we could access the Marketplace with no problems.

HOW TO REPRODUCE

-Open Minecraft Switch.

-Wait a few seconds for your Microsoft account to load.

-Either the marketplace will turn gray saying "Invalid session, try restarting your game" or you can click it but it's loading forever.

-The dression room is loading forever. When you click on it all the skins are default gray and say "0 Minecoins" on top.

MORE INFOS

I tried on the W10 Version and I have no issues

I already reinstalled my game twice, the first time I start it after installing it it's working fine, but if I restart it's stuck. If I join a server then quit, I can see my skins and access the Marketplace. This is not an internet issue but the game itself.
