Thanks
There's currently no implementation of emissive textures with Vibrant Visuals in Java, I think. Using an unsupported by Minecraft resource pack isn't a Minecraft bug. it’s part of the model definition maked by resoruce pack or mod pack.
And you can’t break blocks.
Can Confirm, I add video file because you did not add anything.
It is important to note that the error occurs when you are in survival and adventure mode, but does not occur in creative mode.
Can confirm.
What do you mean exactly? Where is the bug here?
Optifine probably had nothing to do with this situation because it's graphical mod, but it depends on whether you use forge because if so, it may be forge's fault.
Does the issue still persist in the final release 1.21.6?
Could you record the entire process of bug?
Try assigning more RAM to minecraft
Perhaps the villager chose another existing block nearby. I don't know, not enough information.
Try updating Java and your graphics card drivers.
Hey, your bug report is incomplete. Please describe what's going on bad with Minecraft.
