DLLImport causing Editor to Crash if Editor is 2017 or Newer

I'm trying to use a Plugin I developed a few years ago. I'm working in a clean new project in 2019.2.5.1 on macOS Mojave and as soon as I run any function from the plugin using...

[DllImport(pluginName)]
private static extern bool pluginMethodName();

The entire editor crashes and the editor log produces the following messages...

Fallback handler could not load library /Applications/Unity 2017.1.1f1/Unity.app/Contents/Frameworks/Mono/lib/libAssets/Plugins/PluginName.bundle/Contents/MacOS/WiiBuddy
Fallback handler could not load library /Applications/Unity 2017.1.1f1/Unity.app/Contents/Frameworks/Mono/lib/libAssets/Plugins/PluginName.bundle/Contents/MacOS/WiiBuddy.dylib
Fallback handler could not load library /Applications/Unity 2017.1.1f1/Unity.app/Contents/Frameworks/Mono/lib/libAssets/Plugins/PluginName.bundle/Contents/MacOS/WiiBuddy.so
Fallback handler could not load library /Applications/Unity 2017.1.1f1/Unity.app/Contents/Frameworks/Mono/lib/libAssets/Plugins/PluginName.bundle/Contents/MacOS/WiiBuddy.bundle

These exact same circumstances produce no problems in Unity 5.6, but everything 2017 afterwards seems to crash in the same way.

-I've made sure the respective 32-bit and 64-bit plugin bundles are only used in the correct environment in their import settings.

-I see that the error messages are giving a path that is within the Editor application instead of the project hierarchy. I tried adding the plugin there as well and it said I can't have it in both. Then I tried only having it inside the application folder and the Editor gave me a healthy red error saying it couldn't find the plugin.

How should I approach this? I'm not sure what changed with 2017 onwards.

 

Nevermind. I found the problem. Can't find how to delete this thread.
