We did not edit any products or anything else on your site yesterday because there was no need to log in.
Add our email 8themes@gmail.com to list of developers in your Google search console to check your issue in more detail. Also, provide us with WP Dashboard access to check the cache plugin settings. Maybe this is the reason of the issue, not sure.
This plugin https://prnt.sc/1e4r465 is not our plugin but don’t think that this is the reason of the problem with the preview.
