Hi, good day!
When you check your PC to see if it meets the hardware requirements for Windows 11 using the PC Health Check app, it provides real-time information compared to the Windows Update settings compatibility check which runs a scheduled task which will take time to show the actual result.
I recommend using the Windows 11 Installation assistant to upgrade to Windows 11 manually.

Note: It's always a good practice to backup your important files first before performing any Windows upgrade or reinstallation.
Few things to check on the PC
- Unplug all external peripherals except for the Mouse, Keyboard, and LAN cable before starting
- Disable or uninstall any third-party Antivirus program to prevent it from interfering with the upgrade
I look forward to receiving your update and I'm willing to collaborate with you till we resolve the issue. Do keep me informed by clicking "Add comment" below.
