Uncaught TypeError: Cannot read property 'isVisible' of null

[IsidoroMartin]

Hello,
I just installed atom because i was looking exactly what tree-view-finder has to offer.
So i installed atom nor the extension and when i tried to launch it it crashed with the following error.
I am running it on windows 10, and i think that may be the problem. If u look at the path of the files that are shown in the error (~/AppData/Local/...) but idk how to fix it.

Best regards
