No lowest priority node found (path: xx)

Where are you seeing that message?

when I write something, my message is cleared

Can you provide a gif of this behavior?

Hello, i see it in the copilot chat after the upgrade in the release preview. Appears like an error instead of generating the response.

Getting same issue here

I tried installing filesystem MCP tool and gave it access to my Desktop folder. I put a .txt file with a long text and told Copilot to read and analyze it. After that, it failed with the same error message
