Loading bar has missing texture and then app crashes on realm with mod

So, I just made a realm with the modifier “realism craft” by spark universe on the realm. And with that mod, it makes the loading bar have a different texture. The first time I played on the realm, it was fine. But when I tried to join after that, the loading screen was normal, but it didn’t try to connect. It only did for a split second. Then the loading bar has the missing texture, which should not happen. After a few seconds, the music fades out, like it does when you join a world. But then the game freezes for 3 seconds, and then it crashes. I tried to join again and again and again, but there was nothing different. I tried to join the same world but without a realm, but the same thing happened. My sister can join just fine, but I for some reason have the issues. I don’t know if the issue is in my iPad 9, the mod, or Minecraft. Everything’s updated. Pls help
