Impersonation misbehaving - 403 error

Gitlab version 16.7.5

Hello,

There is some bug / issue with on or more accounts in self-managed Gitlab.
Users are reporting that they are unable to visit Gitlab Pages.
When administrator impersonate the user, it returns 403 error. After that, we need to clear the browser cache etc. to reach Gitlab.

Is this could be some Gitlab bug? Does anyone had similar problems?

Thank You.
