EDIT: Here is mu complete malfunctioning code snippet:

var filePath = Path.Combine(_environment.WebRootPath, "Uploads");
if(!Directory.Exists(filePath))
    Directory.CreateDirectory(filePath);

using (var fileStream = System.IO.File.Create(filePath))
    await file.CopyToAsync(fileStream);

Are you trying to create this file into systems folders or similar? Did you try to change your filePath to, let's say your images folder? You need to be sure that you've access rights to write into this folder, otherwise, you might have some issues with Windows permissions.
