ComfyUI doesn't start any longer.

Updated all
Updated ComfyUI
Ran pip install -r requirements.txt

Now I have this:

FETCH DATA from: https://raw.githubusercontent.com/ltdrdata/ComfyUI-Manager/main/custom-node-list.json[ComfyUI-Manager] Due to a network error, switching to local mode.
=> custom-node-list.json
=> cannot schedule new futures after shutdown
FETCH DATA from: /home/jfredr19/ComfyUI/custom_nodes/ComfyUI-Manager/custom-node-list.json [DONE]
[ComfyUI-Manager] All startup tasks have been completed.

Commenting out this from manager_server.py in the glob-folder makes ComfyUI start: threading.Thread(target=lambda: asyncio.run(default_cache_update())).start()

Not sure what it does and how it might affect my installation though 🤔
