Dashboard view cannot be removed


I have a problem with my Dashboard. Since I tried embedding a website directly into my Dashboard as shown below, I have to views (named “unnamed view” and “Strompreis” which I cannot remove anymore. I cant edit them in the editor at all. If I click them, nothing happens.

What could I do to remove these?

Go to raw yaml configuration & remove faulty views manually.
And never ever place a such link there.

Can I edit the raw yaml while the system is running?
I couldn find it in Studio Code Server or editor.

  1. Frontend can be edited while HA is running. In storage mode - ONLY when HA is running.

Thank you so much! I managed to remove it.
