The 64-bit plug-in is mistakenly identified as a 32-bit plug-in by Nuendo

We have developed the Panner and Return plug-ins based on VST3.7.3. The plug-ins are signed by Apple’s enterprise certificate and use the x86_64-bit architecture. However, the plug-in manager of Nuendo 11 often identifies our plug-ins as blocklisted and prompts “32-bit plug-ins are not supported.”

This can only happen if your plug-in crashes when we scan it or if the bundle can not be loaded due to unresolved external dependencies. In case of a crash there should be crashlogs on the systems where this happens which may give you a clue why it crashes.

Nuendo always crashes once upon the first startup after install my vst3 plugins. After the Nuendo is restarted, the Nuendo does not crash again. The attachment is the crash file. Thanks a lot.

hi,Arne_Scheffler can you tell us more something about “plug-in crashes when we scan it or if the bundle can not be loaded due to unresolved external dependencies”?
We step into this bug, InitModule()-BEGIN_FACTORY_DEF-DeinitModule(), in BEGIN_FACTORY_DEF, our project’s VST plugins VstProcessor and VstController are added, Nuendo crashes after executing DeinitModule(), but but VstProcessor ::createInstance and VstController::createInstance are not step in;
How should we do to fix this bug?

BEGIN_FACTORY_DEF (“xxx”,
“yyy”,
“zzz”)

//---First Plug-in included in this factory-------
// its kVstAudioEffectClass component
DEF_CLASS2 (INLINE_UID_FROM_FUID(kVstProcessorUID),
			PClassInfo::kManyInstances,	// cardinality
			kVstAudioEffectClass,	// the component category (do not changed this)
			stringPluginName,		// here the Plug-in name (to be changed)
			Vst::kDistributable,	// means that component and controller could be distributed on different computers
			PlugType::kSpatialFx,   // Subcategory for this Plug-in (to be changed)
			FULL_VERSION_STR,		// Plug-in version (to be changed)
			kVstVersionString,		// the VST 3 SDK version (do not changed this, use always this define)
			VstProcessor::createInstance)	// function pointer called when this component should be instantiated

// its kVstComponentControllerClass component
DEF_CLASS2 (INLINE_UID_FROM_FUID (kVstControllerUID),
			PClassInfo::kManyInstances, // cardinality
			kVstComponentControllerClass,// the Controller category (do not changed this)
			stringPluginName "Controller",	// controller name (could be the same than component name)
			0,						// not used here
			"",						// not used here
			FULL_VERSION_STR,		// Plug-in version (to be changed)
			kVstVersionString,		// the VST 3 SDK version (do not changed this, use always this define)
			VstController::createInstance)// function pointer called when this component should be instantiated

//----for others Plug-ins contained in this factory, put like for the first Plug-in different DEF_CLASS2---
