Based on the information you've given, it seems your computer is not compatible with Windows 11. The error message "This PC can't run Windows 11" generally indicates that the hardware specs of your computer fails to meet one or more of the essential criteria for Windows 11, such as TPM 2.0, Secure Boot, or the necessary CPU support. A good first step is to verify the settings in your BIOS, making sure Secure Boot is on and TPM 2.0 is both present and active.
En effective workaround to fix "This PC can't run Windows 11" error is to modify the registry and remove the restrictions for Windows 11. This can be done by enabling the "Bypass Windows 11's TPM, Secure Boot and CPU" option in WinBootMate. Below is the tutorial and screenshot:

Also, ensure that all external drives and peripherals are disconnected. Proceed to update or reset the BIOS or UEFI firmware to the latest version. During this process, make sure to enable UEFI (if available), disable CSM or Legacy BIOS, and set Windows Boot Manager as the primary boot option. It may be necessary to temporarily turn off Secure Boot and Fast Boot until the installation is complete. Remember to save these changes before exiting.
If these steps don't resolve the issue, consider transferring the hard drive to a different PC for the installation, ensuring it's the only drive connected. Windows 11 is notably flexible when it comes to adapting to new hardware and doesn't typically require an adaptive restore. If the system boots, it will automatically replace all necessary drivers, which may require multiple restarts. Another option is to apply a system image of the same version to the existing SSD or hard drive.
