Hello! I’m working on a plugin for Unreal Engine 5.5 (precompiled build). Everything compiles and runs fine in the editor, but when I try to package the plugin, I get the errors listed below.
After some testing, I’ve narrowed the issue down to a custom audio capture component I created, which inherits from UAudioCaptureComponent. Just including "AudioCaptureComponent.h" in the plugin seems to trigger the packaging failure.
Has anyone run into something similar or have insight into what’s going on? Any help would be greatly appreciated.
