Corruption of a heap - crash detected on Firebase but non reproductable

I have a large part of my users impacted by this crash which is non reproductable. I have only these logs below to help me to investigate. I know that the stack trace indicates that the corruption of a heap may have caused my application to crash but I have no idea to fix.
