Copilot Chat gets stuck indefinitely after a few file creation/editing requests
After updating VS Code to version 1.123.0, I started experiencing an issue where Copilot Chat gets stuck indefinitely during file creation/editing workflows.
The issue does not always happen immediately. If I start a new chat session, Copilot may be able to create or edit files correctly for a short time. However, after a couple of requests in the same chat, it eventually gets stuck in an “in progress / running / thinking” state and never completes the action.
In the latest case, Copilot checked whether a file existed in the workspace before deciding whether it should create or update it. After determining that the file did not exist, it remained stuck indefinitely and never created the file.
Steps to Reproduce
- Open VS Code version
1.123.0.
- Open a project/workspace.
- Open Copilot Chat.
- Start a new chat session.
- Ask Copilot to create or edit a file.
- Confirm that the first request may complete successfully.
- Continue making a couple of file-related requests in the same chat.
- Ask Copilot to create a file that does not exist yet.
- Copilot checks whether the file exists.
- After confirming that the file does not exist, Copilot remains stuck indefinitely in an “in progress / running / thinking” state.
Actual Behavior
- Starting a new chat temporarily allows Copilot to create or edit files again.
- After a few requests in the same chat, Copilot gets stuck indefinitely.
- The issue appears to happen during file creation/editing workflows.
- In the latest case, Copilot checked whether a file existed before deciding whether to create or update it.
- After determining that the file did not exist, it remained “in progress” indefinitely and never created the file.
- The only temporary workaround I found is starting a new chat, but the issue eventually happens again.
Additional Context
I also noticed that the previous Copilot Chat modes/options such as Ask and Plan are no longer visible in the UI after the update.
I am not sure whether this is related to the file creation/editing issue or whether it is an intentional UI/product change, but I am mentioning it because both changes appeared after updating VS Code.
The main issue I am reporting is that Copilot Chat gets stuck indefinitely after a few requests in the same chat session, especially when checking whether a file exists before deciding whether to create or edit it.

Notes
This does not seem to fail immediately in every new chat session. A new chat can temporarily restore file-writing behavior, but the problem returns after a few interactions.
I have not been able to confirm whether this is caused by the VS Code update, the Copilot extension, the chat session state, or the recent chat/agent UI changes.
