The object {objectToRemove} (path: {objectToRemovePath}) is

Error message

The object {objectToRemove} (path: {objectToRemovePath}) is not part of the build profile {path}.

What it means

Thrown by RemoveComponent<T>(T objectToRemove) when the object's asset path does not match the build profile's asset path. The method compares AssetDatabase.GetAssetPath(this) against AssetDatabase.GetAssetPath(objectToRemove); only sub-assets of the same profile .asset file are eligible for removal. A mismatch produces an ArgumentException listing both paths.

Solutions

1. Use GetComponent<T>() to fetch the actual sub-asset belonging to the profile and pass that instance.
2. Use the parameterless RemoveComponent<T>() which looks up the correct instance internally.
3. Confirm the object is a sub-asset of the profile via AssetDatabase.GetAssetPath before calling.

Example fix

// before
profile.RemoveComponent(someOtherProfileComponent); // different path

// after
var own = profile.GetComponent<MySettings>();
if (own != null) profile.RemoveComponent(own);

string profPath = AssetDatabase.GetAssetPath(profile);
if (AssetDatabase.GetAssetPath(objectToRemove) == profPath) profile.RemoveComponent(objectToRemove);

static bool BelongsToProfile(BuildProfile p, UnityEngine.Object o) => AssetDatabase.GetAssetPath(o) == AssetDatabase.GetAssetPath(p);

When it happens

Trigger: Passing an object that lives under a different asset file (or is not a sub-asset of this profile) to RemoveComponent. GetAssetPath returns a different path, so the guard fires.

Common situations: Passing a global/shared asset instead of the profile's own sub-asset; mixing up references between profiles; passing a freshly created instance that was never added to the profile.
