Hi @LeonhardP
i have same issue in Unity 2021.2.8 to 2021.2.15
I asked the publisher from BetterLit and he gave me the hint that the shader compiler is currently broken in 2021.2.x.
Build time from build Adressables and build goes up to 5+ hours.
The PC becomes close to unusable in this time because of 50% to 90% CPU is used.
The Better Lit Shader : Replacement Lit Shader for URP/HDRP/Standard page-5#post-7926304
Could you give us some clarity about this?
