LG G4 gallery app does not open videos

[Peachesk]

I have an LG G4, and recently have noticed that my gallery app does not open videos. This problem is only on the LG gallery app that comes on the phone and not others such as Google photos or quickpic. When you open videos in the gallery, it takes a while to load and then opens up the most recent taken photo or video in your gallery. There isn't a problem with opening photos.

I have tried the following already:
- clearing gallery cache
- clearing gallery data
- rebooting phone

Welcome.

Are you prompted to choose an app in which to open the video?

Are the videos on the sd card or internal storage?

Are the videos taken with the phone's camera or downloaded from elsewhere?
