I was building fine on WSL with Next 6. I just upgraded to 7 and now my build wont work. I use WSL to make builds with paths matching linux.

If anyone else is running into this, try disabling _Real-time protection_ in Windows Defender Security Centre > Virus & threat protection > Virus & threat protection settings > Real-time protection. That finally solved it (albeit not the nicest solution) for me.

@joelugh you can just add the working directory to the exclusion list of Windows Defender, still not optimal but less ugly than switching off real-time protection
