OS version and name: Windows 10 pro
My issue is that the split windows function and the new tab work verry fine till i use a type of watch files command. For example when i run php server from the terminal or i watch scss and css files.. i get this type of error

same issue using bash as shell on windows 10 1803
uninstalling hypercwd fixed this for me
Switching from hypercwd to https://github.com/LeanderFS/hypersamewd fixed this issue for me.
Closing due to plugin related.
