The browser becomes unresponsive when i wants to set the featured image

Hi. My website hadia.id became unresponsive when I wanted to set the featured image in the uploaded file. Every time I open the media is always unresponsive. I suspect because of the protect media feature in the WPDM plugin. What’s the solution? Is there an option to disable protection checks?

I think I know the cause. You are fetching 80 media at a time. That’s what makes the page unresponsive. Can this amount be reduced? Because some of my pictures are big.
