Unity3D error "Invalid Build path"

Question

When I try to build any type of game using Unity, it is giving me this error:

Invalid build path: c:/users/dell/desktop/projects/unity projects/fox the game UnityEditor.BuildPlayerWindow:BuildPlayerAndRun()

It does this with any path

I can't seem to find any reason for this error. I am building on WebGL with 2D graphics.

Version: Unity 2019.1.1f1 Personal

Answer 1

I don't know why it worked but when I chose "downloads" as the exporting path, the error has gone.
