So I was using a texture pack but all the textures are messed up even though I switch versions. I tried disabling that pack but didn't work. And then, I tried disabling all packs but still the same. Please fix this.
You still have the resource pack enabled in the recently added screenshot, can you please disable any and all resource packs entirely, and attach another image?
Please attach screenshots (or even better, a video) of the issue occuring without the texture pack enabled, and F3 open.
