GitHub Copilot Chat Not Opening or Showing Blank Screen — How to Fix
GitHub Copilot Chat may fail to open or display a blank panel in VS Code or JetBrains when the extension is outdated, authentication has expired, or your subscription does not include Chat access. This issue is commonly seen after IDE updates, plan changes, or first-time setups. Following the steps below will get your Copilot Chat panel working again in minutes.
Why does this error happen?
How to fix it
Update the GitHub Copilot Chat Extension
Open the Extensions panel in VS Code (Ctrl+Shift+X) or the Plugins marketplace in JetBrains and search for 'GitHub Copilot Chat'. If an update is available, install it and restart your IDE. Running an outdated version is one of the most common causes of the blank Chat panel, as API contracts change frequently between releases.
Sign Out and Re-Authenticate with GitHub
Open the Command Palette (Ctrl+Shift+P in VS Code) and run 'GitHub Copilot: Sign Out', then run 'GitHub Copilot: Sign In' to generate a fresh OAuth token. Expired or corrupted authentication sessions prevent the Chat service from verifying your identity, which causes the panel to stall on load. After re-authenticating, reopen the Chat panel to confirm the issue is resolved.
Verify Your Plan Includes Copilot Chat
Navigate to github.com/settings/copilot and confirm that your active subscription includes Copilot Chat access, as not all plans provide this feature by default. If your plan does not include Chat, you will need to upgrade to a tier that supports it before the panel will load. Organization-managed accounts should check with their GitHub admin to ensure the Chat policy is enabled at the org level.
Reload the VS Code Window
Open the Command Palette with Ctrl+Shift+P, type 'Reload Window', and press Enter to fully restart the VS Code renderer without closing the application. This clears any in-memory extension state that may be preventing the Chat webview from mounting correctly. After the window reloads, click the Copilot Chat icon in the Activity Bar to test if the panel opens successfully.
Pro tip
Pin both the GitHub Copilot and GitHub Copilot Chat extensions to a specific stable version in VS Code by right-clicking the extension and selecting 'Install Another Version', so IDE updates do not silently break the Chat panel until a compatible release is available.
