Incredibly high crash rate when using CMP with Unity game

[AoC]

Hello everyone,

I'm trying to integrate UMP before January 16th for compliance.

I did it with the Android version of one of my games, and the crash rate increased to 20%/30%, so I had to stop the rollout.

I'm using:

Unity 2022.3.14f1

Admob 8.6.0

Firebase 11.16.0

As mediation parterns, I'm using Unity and Facebook.

It looks like that the crash happens after a Rewarded Video is watched, and I suspect this reading the logs from crashlytics.

I have 2 types of crash logs from crashlytics:

And the other one is this:

This is my implementation of the Rewarded Video:

public void WatchVideo(Action<bool> onVideoRewarded, string source)

{

if (rewardedAd != null && rewardedAd.CanShowAd())

{

MobileAdsEventExecutor.ExecuteInUpdate(() =>

{

Crashlytics.Log("WatchVideo");

this.rewardedAd.Show((result) =>

{

onVideoRewarded.Invoke(true);

});

});

}

}

public void RequestVideo()

{

Crashlytics.Log("RequestVideo");

if (rewardedAd != null)

{

rewardedAd.Destroy();

rewardedAd = null;

}

lastRewardeVideoAdUnit = rewardedAdUnitIds[rewardedAdUnitIndex];

AdRequest adRequest = GetAdRequest();

RewardedAd.Load(lastRewardeVideoAdUnit, adRequest,

(RewardedAd ad, LoadAdError error) =>

{

// if error is not null, the load request failed.

if (error != null || ad == null)

{

Debug.LogError("Rewarded ad failed to load an ad " +

"with error : " + error);

rewardedAdUnitIndex = (rewardedAdUnitIndex + 1) % rewardedAdUnitIds.Length;

StartCoroutine(LoadWithDelay(RequestVideo));

Crashlytics.Log("Video Failed");

return;

}

Debug.Log("Rewarded ad loaded with response : "

+ ad.GetResponseInfo());

rewardedAdUnitIndex = 0;

rewardedAd = ad;

rewardedAd.OnAdFullScreenContentClosed += HandleRewardedAdClosed;

rewardedAd.OnAdFullScreenContentFailed += HandleRewardedAdFailedToLoad;

Crashlytics.Log("Video Loaded");

});

}

public void HandleRewardedAdFailedToLoad(AdError error)

{

MobileAdsEventExecutor.ExecuteInUpdate(() =>

{

rewardedAdUnitIndex = (rewardedAdUnitIndex + 1) % rewardedAdUnitIds.Length;

StartCoroutine(LoadWithDelay(RequestVideo));

});

}

public void HandleRewardedAdClosed()

{

MobileAdsEventExecutor.ExecuteInUpdate(() =>

{

StartCoroutine(LoadWithDelay(RequestVideo));

Crashlytics.Log("RewardedClosed");

});

}

IEnumerator LoadWithDelay(Action load)

{

if (!UmpManager.Instance.HasMinimumConsent())

{

UmpManager.Instance.OnConsentChanged += Load;

yield break;

}

yield return waitForSeconds;

MobileAdsEventExecutor.ExecuteInUpdate(() =>

{

load();

});

}

Can anyone help me?
