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
Applications–>Xcode–>Get info –> Uncheck rosetta and restart system, then it will work perfectly.
Right click on Xcode, Get Info, Uncheck Rosetta. Then quit Xcode from Dock and re open your playground file.
