Can't create character, nor are mine that I have created loading, cant acces marketplace

Minecraft has been broken since the update to 1.18. My created characters aren't loaded at all (screenshot 1) and won't load even after I restart, log out > log-in. I have even tried to uninstall and do a complete fresh install but nothing seems to work.

Also, the character creation area has been fully greyed out and can't create a character at all.

And finally, the Marketplace is not available. Clicking the button doesn't do anything at all...

I have tried everything, from restarting, to reloading, to log out and in, uninstalling and freshly installing the game, deleting everything minecraft related on my pc and a new install and nothing works.
