Error launching Tizen TV Emulator on Win 11 "-enable-whpx: invalid option"

I’m running Tizen Studio 5.0 on a Windows 11 Pro PC. When I try to launch the TV emulator, I receive a popup error message “-enable-whpx: invalid option” and the emulator does not launch.

I've been following instructions from these links:

Installing TV SDK | Samsung Developers

Quick-start Guide | Samsung Developers

I am able to connect to a physical Samsung TV and deploy my app there, but I simply cannot get the emulator to run.

So far, I've verified:

my CPU supports virtualization
hardware virtualization is enabled in BOIS
Windows Feature Hyper-V is enabled

I've tried running the emulator via the command line. I receive the same "-enable-whpx: invalid option" message box, and a bunch of console output. Here is the output:

Any advice on what to try next?

==== UPDATE AFTER FOLLOWING ADVICE ====

After following advice from @Sangwook Lee, I no longer receive the "-enable-whpx: invalid option" error. However, my emulator still does not start. Trying to start it produces two log files, emulator.log and emulator.klog. The .klog file is empty, and here is the content of the .log file:

Solution

Thanks to Sangwook Lee and Jianhua Bi for their assistance. Here is what worked for me.

Environment

Machine: HP Z2 G9 Workstation PC
OS: Windows 11 Pro 10.0.22621
CPU: Intel i7-12700k

Steps

Install Oracle JDK 8u361 x64
Install Tizen Studio 5.0 with IDE installer
Launch Tizen Package Manager, on the Extension SDK tab, install TV Extensions-7.0
Uninstall any installed versions of Intel HAXM via Add or remove programs
In "Turn Windows features on or off" uncheck Hyper-V, Virtual Machine Platform, Windows Hypervisor Platform and Windows Subsystem for Linux
Reboot - enter BIOS
In BIOS, under Security / BIOS SureStart, turn off Virtualization Based BIOS Protection, and under Advanced / System Options, ensure that VTx and VTd are both enabled.
Disable Settings / Privacy & Security / Windows Security / Core Isolation / Memory Integrity; reboot
Disable HP SureClick: right-click HP Wolf in system tray, and disable each of the three options; set Windows services HP Sure Click Endpoint Service and HP Sure Click Host Management Service to disabled; reboot
Ensure all services that could conflict with HAXM are disabled. Run the following in an admin command prompt and then reboot

dism /Online /Disable-Feature:Microsoft-Hyper-V-All

bcdedit /set hypervisorlaunchtype Off

sc config vmickvpexchange start= disabled
sc config vmicguestinterface start= disabled
sc config vmicshutdown start= disabled
sc config vmicheartbeat start= disabled
sc config vmicvmsession start= disabled
sc config vmicrdv start= disabled
sc config vmictimesync start= disabled
sc config vmicvss start= disabled

reg add HKLM\System\CurrentControlSet\Control\DeviceGuard\Scenarios\HypervisorEnforcedCodeIntegrity /v Enabled /t REG_DWORD /d 0 /f

Install HAXM 7.8.0
In Tizen Emulator Manager, launch the TV emulator
