Alert Unable to launch because plugin appears corrupted

This alert message just showed up today. Both in standalone or as a pro tools plugin. Mac Pro 2010 running sierra. Good grief. Any thoughts? Any other info I should provide? This is the inMusic version. Was working yesterday


Still not working. LM is up to date and says that everything is authorized? It works fine on my mojave drive. 2010 cheese grater running Safari. Was working than just quit
