@takazawa-gg It seems that the Line Ads SDK failed to initialize. Given that you're using a debug build and are in test mode, would you try re-installing your app to clear any cached data saved by the Line Ads SDK. If this doesn't resolve the issue, we'll need to contact LINE for further investigation into the error occurring at com.five_corp.ad.t.a(Unknown Source:13). It might also be worth trying to switch to live mode instead of test mode for ad loading.
