Copilot Agent Says "Something Went Wrong" - Nothing I'm doing works

I have refreshed my copilot several times, and even went in to my specific agents to "Update" them to see if that would fix the issue. My copilot works, but my agents still say "Something went wrong" and only allows me to click the refresh button, which ends up doing nothing.

I don't know how to fix this issue and I need this agent to work.

    Hello @Brooke Hill ,
    This appears to be an agent-specific service, publishing, or access issue rather than a browser refresh problem. Try opening the agent in Copilot Studio, run it in the Test pane, and check for a detailed error code or use the Topic checker. Then republish the agent and start a new conversation by entering**“start over”**, since updates may not apply to an existing session immediately.

    Also test in an InPrivate browser and confirm that your license, agent sharing permissions, environment access, and access to any SharePoint or OneDrive knowledge sources are still valid.
