Node error at first run, and then the action disappears from Control Panel

Hi, I have no knowledge of node, but any help is welcome.
Tried remove & reinstall, the same thing happens again.

Error message:

CSScomb error:

I found a bug that would prevent CSScomb: Try online from running, and reinstalled the plugin.
The following error message shows:
