After a standard Minecraft update the world loads but incomplete, including broken addons and the map not loading and the inventory not opening.  This is no longer limited to one world as after just a few minutes every world with addons break, but the thing is I copied the world and removed all of the addons and it didn't fix it and it still was only a 18 x 14 chunks before the map was just gone and into the blue abyss. 

When in the world the ram would spike to 7.3/7.9 GB compared to the normal 5.3 GB on Minecraft and it was using 20 GB of virtual ram causing the SSD to stay at 100% utilization.

I have reinstalled Minecraft and imported the world but it did not fix it.

I have tried removing all addons but the only thing that did was decrease my CPU/RAM/GPU usage.

Normally I would be fine with this because I knew the risks when I added addons a long time ago that forced me to enable experiments, but I have spent over 1 year and a half on that world with almost 400mb of data on that world. I do have a backup that survived but it is from a few months ago.

I just thought of it, does Minecraft have a maximum world size before it has a higher risk to corrupt?

Is there a way to recover my world without having to restore an old backup?

UPDATE:

Here is the link to the world that has the biggest problem as I have recently learned that multiple worlds were affected.

I am not sure if the newest update has fixed it as I have not checked it.
