Looks like your windows install doesn't have access to xdl_diff which is interesting. As a workaround you can revert to the old behavior with:

config.use_internal_diff = false.

Looks like ffi on windows is a bit tricky: https://stackoverflow.com/questions/5919743/how-to-use-luajits-ffi-module-when-embedding

For now we can automatically disable internal diff on windows.

Interesting. As I know, https://github.com/kyazdani42/nvim-tree.lua uses ffi two and works for me on Windows.

But thanks for the reasonable default for now :)
