Same issue that I'm facing after updating Xcode 11.4 to Xcode 12 Xcode 12 macOS Catalina 10.15.4 MacBook Air (2017) Kernel_task is up 100% CPU and Spotlight crashes. Can anyone have temporary solution for this?

That is the same thing happening here, Apple developers please response immediately with estimation at least.
