Hey there,
please try to use english, so everyone can understand your issue. You can also use translation and AI tools like DeepL or chatGPT to translate.
I changed your titel to english and here is the translation from your post:
I had created a kingdom, but the game updated and I lost everything, and I couldn’t find the data.
not sure when you last played, but with the breach update on april 30th the old realms and characters were not compatible anymore. a lot of systems had been changed and creating a new character and realm was necessary to access the new content, see here: Wicked Legacy Branch
