Access Denied when moving Folder from a document library to another

We have 2 Document Libraries inside our classic online team site, as follow:-

1. Lib A which have content approval on.
2. Lib B which have content approval off.

Now if a user with contribute permission on both libraries tried to move a folder from LibA to LibB using the modern "Move to" feature, the user will get this error "Access denied.You Do not have Permission to perform this action or access this resource":-

While using the site admin user, i am able to Move the folder.. any advice on this weird behavior? Thanks
