Hi Diksha, I did not get you can you please eblobarate? This issue we are getting when we try to move the published assets in bulk usually 6+ at a time from one folder to another , it keep spinning in move wizard and we can see 500 internal server error in console. We are using AEM 6.5.5
This is related to CQ-4286779, on selecting all assets and move them from one location to another, asset UI spins indefinitely. The issue related to bulk asset move operation only occurs when there is a page or more pages have conflicting references.
