Since I cant reopen previous issue and there was no response, I create duplicate of this - #3438

Important update to previous issue:

1. 351 - is completely different issue with completely different stack
2. App Lovin team already confirmed that this crash is on AdMob side - crash on ios 17.4+ AppLovin/AppLovin-MAX-SDK-iOS#330 (comment)

@OldSlash

Can you provide me a sample of your reward callback and show call? I am asking because the last line in the stack trace is TenisArena which is right on the borderline.

Update - it seems that crash is fixed in iOS 17.6.1. At least we observe only about 0-2 crashes per day and only on iOS 17.5.1 and earlier after august 10th , so now it's not a problem for us.
