Incorrect homepage styles after fresh install

I get incorrect styles for the home page when I visit my store URL. See below. Under notifications, there is a message saying: Cannot read properties of undefined (reading 'response'). How can I fix that?

Go to your sales channel, open your theme, save it and the css will be compiled again.

The „Cannot read properties of undefined (reading ‚response‘)“ is a error in the Shopware backend. It hopefully will be fixed in the next update.
