Premiere crashes when putting a transparent png into timeline

Hi

I make a lot of videos for social media, and as you know, a large amount of the screen is hidden in 'like buttons', video captions, etc. on SoMe. So when I edit I use this transparent safe-area png made in InDesign.

This is where the problem occurs.

For some odd reason, Premiere can't handle this. It's impossible to edit anything when I put this on the timeline. But I need to attach it to see what will be visible on SoMe. 

When I turn it off, I can continue editing. The file is 350kb. so it should be easy riding for Premiere, or any editing program made after 1990....
