My PTR 1.30.1.10151 was working fine until the Windows 10 Version 1803 - Build KB4457128 update.
That Windows 10 Version 1803 - Build KB4457128 was released today on the 11th of September 2018 and coincidentally, the PTR stopped working right after downloading that new Window's build.
It says there is an error "0" and there is absolutely no way to open the application anymore.
