Embedded binary is not signed with the same certificate as the parent app. Verify the embedded binary target's code sign settings match the parent app's.

Verify the embedded binary target's code sign settings match the parent app's. I don't know the real issue.

Having an embedded executable in your parent bundle with a different signature is generally not a recommended path. If you are pulling in an embedded executable to your bundle, you should sign it with your Team's Signature. I would also avoid using the disable-library-validation entitlement as this can lead to other strange issue coming to light.

In some cases you may need to code sign different parts of your project by hand, if this is the case, Quinn has a great example on how to do this here.
