Issue with Video Playback After Packaging

Hi,
I am still a little new to game design so if I struggle I’m sorry ahead of time.

The video format is an MP4 file. The size is 192 MB.

I attached a photo below of blueprints of what I used

I have the WeBM Video player plugin player enabled, but I don’t know if it’s doing anything. I tried using that solution a while ago.

Where do I check the drivers? I tried on a different computer and it’s the same issue where I can hear it but not see it.
