This error occurred when I double-cliked a file to open while Untoggle(Packages -> Activate Power Mode -> Toggle) or Disable(Packages -> Activate Power Mode -> Disable) state.

P.S. Sorry. There seem to be some conditions which this error occurs. I'm using "symbols-tree-view" package and "Minimap" package. After I repeatedly untoggled and toggled these packages, then this error didn't occur.
