NullReferenceException: The Table "xyz_en" does not have a SharedTableData

So, I created a simple example to demonstrate the error.

There is a build and source code (re-import packages before using). I also shared two videos. The first video demonstrates how it works in the editor, the second video shows errors in the browser.

Code:
