Can you see it now?
I think the message in English is "There was a problem charging the world"

Hello?

I can see the screenshot now. Do you also get this message when you try to create a new world or join a server? If not, what happens when you try to create a new world or join a server?

I realized that I can create new worlds and enter servers if I dont try to enter one of my old worlds first. but I dont want to do all the things I did in my survival one more time, I already did that twice, please help

We're tracking this issue at MCPE-117062, so I will resolve and link this ticket as a duplicate. Please see this comment for a potential workaround.
The screenshot didn't get attached to the ticket. Could you try reuploading it?
