Hey there! I hope you can help me 🙂

I got a weird Error in my app. The Problem is, I can not reproduce this crash. SOmetimes it does not crash and sometimes after five interactions.

I hope someone can read this log or can help me how to figure out what it could be ✌

This is my log for this crash:
