Issue with Code Suggestion Acceptance Not Working

Previously, when I accepted a code suggestion, it would update my code directly. Now, clicking “accept” only causes a brief highlight on the page without any changes to the code. This issue doesn’t seem to relate to key bindings, as I noticed a similar suggestion in the GitHub issues list that didn’t resolve my problem.

Is this using cmd-k or the apply feature from chat? Do you see the updated code, but hitting accept reverts the changes?
