v4.0.0a2 'NoneType' object has no attribute 'get-uf2_ctx' (Windows 10)

I am working with RTL8710BN (AmebaZ) and get this error when using the ltchiptool in Windows 10 with FTDI serial cable connected. Unable to get this working, so I'll move back to my Linux machine and update the tools there.

This is a bug, which I fixed some time ago but probably forgot to push the changes. If you go to "write flash" and select a file there, the error will be gone and reading should work again.

Fixed in v4.0.0a3.
