Lightweight Render Pipeline "Compiling shader variants"

Im currently using Unity 2019.3.0a7 and using the LWRP for the first time. I created a new project with the template. Im using the default scene and changed the build target to Android and checked VR (Oculus mobile).

When I click on Build&Run the build takes forever with the “Compling shader variants” dialog. I waited over an hour and it was still not done (btw clicking on cancel crashes Unity). Im not sure if this is a bug or if this is supposed to be “normal” with the LWRP, but I have never seen any build take this long (the default scene is almost empty).

Does anyone know a solution?

The long compilation times are a known problem. Have a look at this thread and reply for more information and ways to improve them in your project:

The crash upon cancelling the process has been fixed in the upcoming a9 release.
