The path for the registered object is too long. It’s a limit from the OS. You can make the filepath shorter by moving your projet near the root. I always put project at C:/
As @Nilau said, this is a restriction of your operating system. Prior to Windows 10, this limit is 255 (thereabouts, sometimes you can get to 260). If you are on Windows 10 however, you can increase this limit.
I would recommend Nilau’s advice though, and just move your project closer to the root directory.
Thanks to all.
