Hi there, I would like to please request some help with the following issue.

Product: SDL Trados Studio 2019 Freelance SR2 CU8 (15.2.8.3007)
Operating system: Windows 11 x64 (ASUS Zenbook S 14 UX5406SA, Intel Core Ultra 7 258V)
I successfully deactivated my licence on my old laptop via my RWS account before installing on the new laptop.
I downloaded the latest available installer from my RWS account and performed a clean installation.
The installation completed successfully with no errors.
Online activation fails every time with:
"Activation failed. Could not connect to the activation server. Check the activation server address in the provider settings. The remote server returned an error: (403) Forbidden."
The Internet connectivity check succeeds.
Offline activation also fails:
No Installation ID is generated (field remains blank/greyed out).
Entering the activation code causes the error:
"The requested service is not available: Sdl.Desktop.Platform.Services.ITelemetryService."
I have already:
uninstalled and reinstalled Studio,
restarted Windows,
run Studio as Administrator,
confirmed that the licence was deactivated on the old computer.

Could a moderator please check my licence/activation record or open an internal licensing support case?
