Can’t send a prompt in a chat mode

Good day! Five hours ago everything worked fine. Now I can’t send a message in my old chat and also can’t start a new chat. To the left of the prompt area I see a symbol— “a crossed key”, if I click on it it says “unlink or switch api key here”. Today I send two short prompts, so logically it doesn’t look like I gave a quota problem. I’m in free tier, but previously I have never met such an issue. I use 2.5 pro model. But right now no matter what model I choose, I can’t send a single prompt. In AI Studio UI it’s still said that AI Studio is free. Could anybody please explain, what happens?
