Prose gone when changing file and running the code

so i tried to add a simple prose onto my playground project
Code Block
/*:
Roses are `UIColor.red`,
Violets are 🔵,
Swift Playgrounds are rad,
and so are you!
*/

but when i run my code or go to my sharedCode.swift, the prose vanish

Is there any setting that i need to do? or is it an M1 problem?

Thank you
