[BUG] Cant register PnP Management Shell in new tenant

[Stefan1891]

1. I'm not able to register PnP Management Shell in Tenant X but works just fine in Tenant Y.
   They shoud be identical in configuration in regards of the Enterprise Apps
   Both tenants are on Entra ID P2 and hold Microsoft 365 E5 licenses.
   The running account is active Global Admin.
   There is no MFA on that account.
   The PnP Management Shell doesn't exist prior running Register... in any of the tenants.
   Its possible to register other applications like 'Microsoft Graph Command Line Tools' or any Enterprise App in the gallery.

The error is

The tenant that works

The tenant that not works

Not able to find the reason why it doesn't work in the newest tenant.
