Aero Flip 2D stopped working

Question

The Aero Flip 2D does not work anymore although the Flip 3D does . When I press Alt+Tab I only see the classic list of active tasks:
And I cannot use the directional keys to select a task.
Facts about the problem:
Only one user account is affected.
The Desktop Composition is active .
Ctrl + Alt + Tab does not work.
Ctrl + Win + Tab works and shows the Flip 3D .
All other Aero effects work well: Flip 3D, Snap, Shake, Peek, ...
Verifications that have already been made:
$> chkdsk /f c:
Aero troubleshooting.
$> sfc /verifyonly
$> gpedit.msc   . Nothing prevents Aero from working properly.
All the relevant services are active: DWM, Themes.
$> eventvwr -> Logs -> Application. The Desktop Windows Manager did not generate any important events related to the problem.
None of the verifications above has detected any problem.
I have been using Desktops 2.0 since a few weeks ago. Deactivating Desktops did not solve the problem .
I will only create another user account as a last resort, so I hope someone can help me.
To informatize is necessary; follow me the good.

aharrell905,
I'm sorry to hear about your phone! It does appear that there may have been a hardware concern happen. We likely have several options, including the manufacturer warranty. The warranty covers these sort of situations for 12 months after the original purchase of the device. The account may have an available upgrade, too! If you need assistance with reviewing your account for options, please direct message me.
Thank you!
