Did you try going back to the prior Forge version? It looks like you updated Forge.

[01Mar2021 08:31:33.354] [Render thread/WARN] [net.minecraftforge.fml.FMLWorldPersistenceHook/WP]: This world was saved with mod forge version 34.1.42 and it is now at version 36.0.14, things may not work well

EDIT- I am not saying that as a fix, but wondering if the issue still exists go back to the 1.16.3 version.

I don't see an issue here?
