Cannot use Hypervisor with inherited app sandbox

I have a main app with the entitlements:

• com.apple.security.app-sandbox

• com.apple.security.hypervisor

and a helper app with the entitlements

• com.apple.security.app-sandbox

• com.apple.security.inherit

According to the documentations, if I start the helper app with NSTask, it should inherit the sandbox and I do see that for file accesses. However, when I try to use Hypervisor.framework, I get HV_DENIED.

If I try to add "com.apple.security.hypervisor" to the helper app, then the NSTask spawned process crashes with Could not set sandbox profile data: Operation not permitted (1).

I believe this is a bug and have submitted FB8921623

In the meantime, is there a workaround other than disabling App Sandbox or sticking to a single app (not possible for our application)?
