Describe the Bug
Created a few different custom modes that used to work just fine. Now they don’t. “Agent” works just fine. When I try any other custom mode and enter chat and send, it says Generating for a second then goes away and returns to the chat box with my typed text with no results… Like I entered the text in chat but didn’t press enter. Switch back to Agent and Agent works. Back to custom and still does not work. FYI I have Pro.
In developer tools Console I see the following when I submit a chat with a custom mode:

Yes - Cursor is unusable
