Error while restoring files from Trashbin

I am using NC version 15.0.2.
I am getting below error when try to select multiple files (more than 2) and then restore them. Files were gone in loading state and when i refresh link, selected files are restored.
Is this application bug or something has changed in nextcloud back end files by Admin?

IS there any solution to this issue, i also having this problem. i currently at version 16.0.4

Check-out want is written to the Nextcloud log file if this problem appears.Hopefully it gives you a hint whats going wrong here.
