A bunch of "not defined" errors

I had started the app for Minecraft Bedrock Edition 1.17. When I started it, I noticed it hung on 98% for a bit. Then, it loaded up. I saw a bunch of errors that seem like they are related to textures, but IDK. I restarted the app, and nothing popped up. I think it was a one time thing. Can someone tell me why this happened?
