Assertion failed: SUCCEEDED

You know, I’m surprised I don’t see a forums option for errors. Probably would be really useful!

I am a BIONICLE fan. For those who don’t know, BIONICLE was a toy line released in 2001 by the LEGO toy company. Along with it came an incredible storyline that developed a massive fanbase. So much so, a person who goes by the name JoJordan is creating a game via the Unreal Engine called BIONICLE: Masks of Power, based off of the comic books of 2001.

However, I’ve come across an error. One which he has no idea what it’s about. I was wondering if anyone here can help.

This is what the error says:
Assertion failed: SUCCEEDED(HResult)
[File:D:\Build++UE4+Release-4.16+Compile\Sync\Engine\Plugins\Runtime\WindowsMoviePlayer\Source\WindowsMoviePlayer\Private\WindowsMovieStreamer.cpp] [Line: 457]

If anyone has any info on what this is about, could you please reply! I’ve really been wanting to get in and try fighting the new creatures he’s added!

Thanks!
