Where do I start with Android logcat logs for crashes?

Question

My game previously worked well on Android, but after some significant changes, a recent build now unfortunately fails. I learnt how to view debugging via logcat, but unfortunately cannot make sense of the following error, which occurs during/following the interaction to LoadScene:

Any advice on my first Android debugging would be much appreciated, thank you.
