Cant join Singleplayer Worlds anymore 1.19.2

Well today i tried to Export my Mod so friends can play it,

 

I tried it out to see if it works, but i couldn't join a singleplayer World and always "Invalid player data" was shown and after that "Disconnected",
Now i cant even join a World in the Test Run in Mcreator, and the same things are shown

 

I tried it earlier and it works but it stoped working after i tried to export it

 

It would mean alot if someone could help me pls,

thanks
