"Unable to launch ./UnrealEngine/Engine/Binaries/Linux/ShaderCompileWorker - make sure you built ShaderCompileWorker." on Ubuntu 21.04

In case anyone comes across this in the future, this question helped resolve the issue UE4Editor error - no ShaderCompileWorker binary - Platform & Builds - Epic Developer Community Forums

I had to run ./Engine/Build/BatchFiles/Mac/Build.sh ShaderCompileWorker Linux Development, which build the ShaderCompileWorker.
