Can’t deactivate properly

I installed this plugin to try it out and first thing I did was go to the media area of wordpress. All images were gone (not displaying).

I decided to play it safe and deactivate the plugin to make sure the images were not lost. I could not deactivate it.

When I click deactivate the page gets a dark overlay with nothing else on it. If I click anywhere in the page the dark overlay goes away. No way to deactivate.

I had to go into file manager and rename the plugin folder. My images were displayed again in the media area and the plugin showed as deactivated. I since deleted it.

I have read other posts saying they had their images disappear and it seems like it causes wordpress to no longer be able to locate the images even though they may still be on the server. I am not convinced it is safe to use. It’s sad because it looks quite nice but I am not willing to risk losing all my images because its not working correctly.

Has anyone else encountered this issue? Surely it cant be normal behavior. I am using default wordpress theme 2017. Thanks.
