This could have something to do with WSL reporting the permissions of all files on the Windows filesystem as being 777. Git then regards all files as changed because their permissions are different.

Try changing the Git configuration so that permission changes are ignored:

# For the current repository
git config core.filemode false   

# Globally
git config --global core.filemode false

You can set git to only use CRLF line endings with:

git config --global core.autocrlf true
