Using vim-vinegar or trying to use :e . will crash nvim

Question

I have recently transitioned from vim8.X to nvim0.4.4 and so far I've been extremely impressed with the development experience.

One feature I'm really missing is using vim-vinegar to exit the current buffer and jump to another file in the current directory (or browse up the file tree with -)

Whenever I currently try to run :e . to browse the current directory, nvim will crash.

I've attached my init.vim incase I've configured something wrong

set nocompatible
filetype off

This was resolved by updating to the 0.5.0 nightly build. There is an issue with netrw in 0.4.4
