Hello,
Thank you for reaching out to the Microsoft Community and I'll be glad to assist you today.
I understand that your Windows 11 computer is stuck in a restart loop with the spinning circle, and even a forced restart by holding the power button isn't working.
If forced shutdown did not resolve your issue, make sure you can boot your PC in the Windows Recovery environment by following the steps below.
- Start your device and wait for the Windows logo (or the manufacturer's logo) to appear.
- As soon as the Windows logo appears, press and hold the power button until the device shuts down.
- Turn your device on again and repeat step 2.
- Turn your device on a third time. Windows should display the Automatic Repair screen.
- Select Advanced options.
You can try recovery options like Startup repair, System restore or boot your safe mode to resolve the issue.
If this method does not work and the device keeps spinning, it is recommended to create a USB Windows 11 Bootable installation media from a Working computer and use the drive to Repair your Older operating system
Create a Windows 11 Bootable Installation media using the Media Creation tool (MCT)-

• Plug in the USB Bootable Installation media on the problematic PC and boot from it.
• Select Repair your computer option instead of Install Windows.
• Your device will boot into the recovery screen and you can try the recovery options listed there.
For reference, you can check the Windows 11 clean installation article for reference on how to create a USB bootable installation media and boot your USB drive.
