What do I do about this error message (Minecraft for Nintendo Switch)?

I play Minecraft for the Nintendo Switch, but I get error number -9 when I enter the game. The text then appears, indicating that an error had occurred and the software was therefore closed. I know that this error number reports an error in the marketplace. However, I have not yet found a page that could really help me with this problem. As long as the error is not fixed, I can't join the game. Did you have the mistake? Even before or do you know how I can fix it relatively easily?
