How to -disable-dynamic-actor-isolation FLAG

I built my app with Xcode16 and now the app is crashing. I suspect that the dynamic actor isolation check is the cause, so I'm trying to set the "-disable-dynamic-actor-isolation" flag, but the app crashes, so I don't think I'm setting it correctly.

How to set "-disable-dynamic-actor-isolation" flag?
