Peacefully mining out a massive crater when my game crashes, and I get an error code "-1" with the error menu saying,
The game crashed whilst rendering entity in world
Error: java.lang.NullPointerException: Cannot invoke "net.fabricmc.fabric.api.renderer.v1.Renderer.meshBuilder()" because the return value of "net.fabricmc.fabric.api.renderer.v1.RendererAccess.getRenderer()"

Reading through the crash report, the game crashed due to a falling gravel block. I've sent my crash report if this helps.
