Some of the user even though they are admin not able to view the page "License Workbench" instead see the error "You do not have permission to use this page" like below.
Release or Environment
Software Asset Management plugin installed.
The issue might be due to an invalid user preference. We are able to validate this by removing all the user preferences for this user and the user is able to see the page.
This particular use case the invalid user preference is "glide.ui.accessibility", the value should be true or false for this but this case its left empty.
Removing the user preference fixed the issue.
