I'm running Minecraft (v1.16.4002.0) on a Microsoft Surface Pro 3 and having issues exporting my Minecraft world.

In the game, I click on the world I want to export and the process is successful. However, once I go to the exported file it's showing 0 KB versus my previous exports that are a few hundred thousand KB file size.

To test importing the 0 KB file, it briefly pops up saying "Level import started", then another message that says "Level import failed."

I've had this issue exporting worlds for backups in the past but have had it work randomly with no rhyme or reason. More times than none though it fails to export despite showing a successful export in-game.
