The block textures got messed up

I closed my Minecraft world without saving it properly (instead of using the Save and Quit option, I just exited Minecraft). When I logged on again, all of the block textures were completely messed up. Berry bushes had the texture of netherrack gold ore, spruce wood had the texture of a loom, grass blocks had the texture of a green candle (I think), grass had the texture of lime shulker boxes… you get the idea. When I broke the blocks, they still made the same block noises and same particles (for example, clay looked like blue glazed terracotta, but when I broke it it still made the sound of clay breaking). They didn’t drop anything because I was in creative. I left the world and then joined it again, and all of the textures were back to normal. This world had the Happy Ghast and Vibrant Visuals experimental features on.
