Whare are the Audio Unit disappear?

After updating to the latest version, the Audio Units I am using disappeared , and there is no way to bring them back
I am on new Mac mini 6 core I7 tuning on Mojave, any idea ?

OK found the problem , there was a plugins that didn’t load because of authorization question, the question was in a small window behind the main window so I didn’t see it, it will be good not to use popup in this case.
