Hi @Vicky_Tan,

Please reproduce the issue, collect recent SharePoint logs and send them to [email protected] with the link to this community thread.

They are usually located in this folder:
C:\Program files\Common Files\Microsoft Shared\Web Server Extensions\15\LOGS
or in this folder:
C:\Program files\Common Files\Microsoft Shared\Web Server Extensions\16\LOGS

This will help us to understand the issue better.
