Hi @7SwordsDev , can you share the full stcktrace for the crash. That would help us debug the issue further

I use applovin and add mediation to use it normally. However, when I put the product on the appstore, firebase crashlytic reported a crash and this message. Besides that, I don't have any further notes.

[santoshbagadi]

You should be able to get the full stacktrace from firebase. There would be a TXT button that you can use to get the text stacktrace.

[7SwordsDev]

Do you mean this txt is correct?

Yes, this is helpful. Could you also share the list of all the adapters included in the project (a screenshot of our Integration Manager).

[7SwordsDev]

Below is the list of adapters that I have integrated.

Hi, we got the same report from other developers and they noticed this started when they added Moloco. At the moment we have a theory that Moloco introduces something into the build that ends up breaking JSON in some way and leads to the crash.

Given the above integration manager screenshot, you integrated Moloco in this affected build as well. Would you mind trying uninstalling Moloco and see if the crashes still persist?

In the meantime, we're investigating together with Moloco and I'll let you know if/when we find the underlying issue.

I will try this. Thanks!
