2022 Elements Slideshow Export failure

[jimfromsdca]

I created a Slide show with about 180 slides and have tried to Export it to a file.  The mp4 file gets created, but is invalid.  Double-clicking it an error message pops up saying it is an invalid file. The error code is 0xc00d36c4. Tried Exporting as 720p and 1080p.

Can you play the mp4 file in other software?  Try the VLC media player.  (It's free to download.)
