In the URP it crashes like any standard unity material shader with the neon pink. This is normal for unity, as you have to update the shaders when working with URP. And even so, don't know it it is because of the URP pink, but it still isn't double sided. I'm using Unity 2019, maybe that's why. I refuse to use the new buggy unity versions like 2020.
