Recently, since the latest update of Fabric API(i believe), my worlds have stopped loading to a certain point. All entities(zombies, sheep, etc) all freeze. Blocks no longer drop, y'all know the works. Upon closing the world. "Saving world..." indefinitely. I tried this alone with Fabric API and (obviously) Optifine, and it has the same issue. Switching to Sodium fixes this issue. Is anyone else having this same issue? Thanks.

Do you have any logs from when this happens? This is a classic sign the internal server has crashed
