The game works fine on my phone, but it couldn’t work on other phones. I saw this error: [https://i.ibb.co/bvQsBvs/Ads-z.png](https://i.ibb.co/bvQsBvs/Ads-z.png)

I solved this error by doing this: [https://i.ibb.co/FwhZwf0/bas.png](https://i.ibb.co/FwhZwf0/bas.png)

Now I don’t get the error, but my main character in the game; other actors, zombies, some textures etc. does not appear, like this: [https://serving.photos.photobox.com/93975294d41487962371a0c6f24a0652db67007194f2465317704e181128e8bf133e05f7.jpg](https://serving.photos.photobox.com/93975294d41487962371a0c6f24a0652db67007194f2465317704e181128e8bf133e05f7.jpg)

What should I do? Please help. I searched but couldn’t find ANY solution.

(Also, I cannot switch to Android ES2’s preview mode in Unreal Engine. The program freezes. And it shuts down.)
