I can't run any Xcode Swift Playground project without getting the error:
Failed to launch process. Failed to attach to stub for playground execution: error: attach failed ((os/kern) invalid argument)
Does anyone know how to solve this?

I've the same issue. If I launch Xcode using rosetta, it doesn't show anything. You must switch off rosetta and it works perfect.
To expand on @E.P's answer
To put off rosetta Go to Aplications-->Xcode-->Get info --> Uncheck rosetta.
You need to restart the system in some cases.
