Change AR feature at runtime

I want to build an AR experience where I have 4 button and each button activate one of the following: obj recognition, image recognition, GeoAR and instant tracking. I started to implement the first two buttons that allow the user to choose beetween obj and image recognition. When I load the first tracker the app runs fine. The problem is that when I create a new tracker the app crashes with an error that look like a free of and invalid portion of the memory. I sent you a more detailed report of the error in another post. I also sent you the code on that post. I'm using JavaScript wikitude sdk 8.5 on Xiaomi redmi note 7 with Android 9.

Update: the crash occurs only when i switch from obj recognition to image recognition, but It works fine when i switch from image recognition to obj recognition.
