When I try to Run Minecraft Java 1.16.3 (latest edition) It boots up the Mojang loading screen and the it freezes and says "not responding" at around 75-95% on the loading bar. it seems to only do this for the latest version, I've successfully run it on version 1.2.1. 

-Unable to render embedded object: File (UPDATE) not found. I've resolved this issue, you have to:

1.Start Minecraft.

2.When Minecraft fails to load, open Task Manager (you can access Task Manager by Right-Clicking on your Task Bar.

3.Find Minecraft Launcher in Task Manager (there may be more than one).

4.End Task Minecraft Launcher(s)

The Game Should continue loading and start as usual.
