Latest version of Behavior Designer Pro completely broke on my project

[Lasovar]

My coworker said the package had a few bugs so I thought I would upgrade so maybe that would solve them... but the behavior designer window broke and it shows nothing on existing and new behaviors and it's throwing a bunch of errors in the console


The error: `TypeLoadException: Could not resolve type with token 010000d4 from typeref (expected class 'UnityEngine.EventModifiers' in assembly 'UnityEngine.IMGUIModule, Version=0.0.0.0, Culture=neutral, PublicKeyToken=null')`

I have no idea what's going on or even how to debug it... the call stack just leads to `GUIUtility.ProcessEvent()`
```

This is the full call stack if it helps... this is now a huge blocker to multiple team members so I need to resolve this ASAP

Edit: to note, the errors don't spam always it's on events like mouse down, scrolling, etc...
