AR Scene crashes on start after loading the scene successfully multiple times.

Hello, first post so sorry in advance if I don't provide the correct info.

I am building an AR app in Unity 2019.2.12 with AR Kit XR Plugin 2.0.1

When the AR scene starts for the first time after the app is launched there is no problems. Ill mess around in the scene for a while then exit to the main menu. When I relaunch the AR scene sometimes the app works fine but other times it will crash. If I repeat, eventually the app will crash. I am using the GenerateImageAnchor script that is built in to the AR Kit Plugin, and just before the crash the concole log looks like this:

Seems like the GenerateImageAnchor Script is trying to remove an image anchor even though I just loaded the scene and there shouldn't be any active.

Been stuck on this for a few days and would love any help. Thanks.
