The game does not start on android 11

The game stopped starting after I added the save and load option to it. The game starts on android 8.1, but does not start on android 11 - crashes without error. Also, a UE4Game folder with logs is created on android 8.1, but not on android 11. Version UE - 4.25. Please, help.

This is how my save file is created in GameModeBase:





<ul>


<li>

void AMyGameModeBase::CheckSave()

</li>
<li>

{

</li>


<ul>


<li>

if (UGameplayStatics::DoesSaveGameExist(TEXT("save_01"), 0) == true)

</li>
<li>

{

</li>


<ul>


<li>

GEngine->AddOnScreenDebugMessage(-1, 5.0f, FColor::Green, TEXT("Savefile already created"));

</li>
<li>

return;

</li>


</ul>


<li>

}

</li>
<li>

UMySaveGame* MySave = Cast<UMySaveGame>(UGameplayStatics::CreateSaveGameObject(UMySaveGame::StaticClass()));

</li>
<li>

UGameplayStatics::SaveGameToSlot(MySave, TEXT("save_01"), 0);

</li>
<li>

GEngine->AddOnScreenDebugMessage(-1, 5.0f, FColor::Green, TEXT("Savefile created"));

</li>


</ul>


<li>

}

</li>


</ul>
