Fixed when running "Update All" in "ComfyUI Manager" and manual git pull. Then you can update normally with "update_comfyui.bat"

This issue appears to have occurred because you were not on the main branch.
(If you restored using the snapshot feature, this phenomenon may have occurred as it forcibly adjusted to that version of ComfyUI.)
In the case of ComfyUI-Manager, it has a feature that forcibly readjusts to the main branch even if you're not on it, which is why it was resolved.
