ImGui doesn't render, and the game crashes upon screen touch

[0x256e4]

Game : Blue Archive Lib : il2cpp.so

how to fix this issue?

maybe the input symbol isnt found, you can try finding the "nativeInjectEvent" pointer using kittymemory's nativelib scanner to enable proper touch.

for the rendering part, make sure that the game uses egl (opengl 2.x/3.x) if not you'll need to find a different render buffer method to hook to.
