Only specific users are not able to access VTB home page. - /nav_to.do?uri=%2F$vtb.do
One of the VTB created by the user on a specific table, the table itself got deleted. Hence VTB home page is unable to render that particular VTB .
This VTB is defined on a non-existing table and owned by the user who is facing the issue.
Hence the issue is happening only for this user.
Deleting the VTB. (since it is present on a non-existing table)
Deleting this VTB would trigger cascade deletions in VTB Cards, VTB Lanes & VTB Labels tables as well.
