Apache unresponsive when using NFS on Windows with Homestead

I'm using Laravel Homestead (Vagrant) to set up my development environment. Everything works fine, until I try setting up NFS on my Windows following https://laravel.com/docs/8.x/homestead#configuring-shared-folders

As soon as I set up NFS, the vagrant up process goes fine, but trying to access the project website makes it unresponsive, i.e. no reply from the server. Opening vagrant ssh, only the place where the shared folder is present is unresponsive (bash gets unresponsive), otherwise other parts of the shell keep working.

More than a day of debugging later I find that simple files are actually working fine. So if index.php contains phpinfo();, that loads fine. I then copied the Laravel public folder, all good with an error that vendor is missing. Added the vendor folder, still good, says Kernal missing. And finally when I add the app\Http\Kernal.php file, again it gets unresponsive. I don't think its got to do with Kernal.php, more like, when a certain number of files have opened it gets stuck (I could be wrong here). Without NFS, I've been using Homestead for years without issue. But I definitely want the speed increase
