Shader pack causes weird colors even after deletion

I used a shader pack on Minecraft Bedrock (Android) and it caused weird colors and lighting in the game. I removed the shader pack, uninstalled the game, and reinstalled it — but the problem still persists.

Interestingly, my sibling used the same shader on their device and had no issues. This leads me to believe the problem may not be the shader pack itself, but possibly a bug in my Minecraft installation or how it handles graphics after an update.

Please help identify and fix this issue. I'm using Xiaomi 14T with Android 14, and this started happening after the most recent Minecraft update.
