Taskbar Only Works on Secondary Display (Win11)

Greetings,

Since plugging my Eluktronics MAX-17 with Win11 Home into my television via HDMI, my main Primary laptop display's Taskbar is blank, black, unclickable and off to the lefthand side. However on external monitors it shows clearly the correct way. I've tried flipping Taskbar settings around in various ways but nothing corrects it.

TLDR: I've tried the many troubleshooting steps available online, see below for a list.

BACKGROUND:

• No new software or driver updates involved:
  
  • I merely linked my W11 Eluktronics MAX-17 laptop to my TV via HDMI, and since it accepted the external display my Taskbar went off to the left side of my primary display, and became bereft of all app icons.
    
  • The overflow section still appears to have some app icons in it, but barely just.
    
• Clicking on the blank Taskbar does nothing. Right-Clicking also does nothing.
  
  • However, the real Taskbar will show only on an extended display, not on the primary, if I connect one:
    
  • If I have the external connected, I can switch my secondary to primary and it *looks* like it's fixed, but that obviously goes back to normal once unplugged and my primary becomes the de-facto primary again.
    

STEPS TRIED:

• Chose all alternate options under actual Taskbar settings by enabling/disabling Taskbar on all monitors, etc., reducing resolution, simple troubleshooting.
  
  • Note there seems to be less control over Taskbar behavior in W11.
    
• Restarted the Windows Explorer service, and related processes:
  

ShellExperienceHost.exe (couldn't find this one)

SearchIndexer.exe

SearchHost.exe

RuntimeBroker.exe

• Used CMD >> reg delete HKCU\SOFTWARE\Microsoft\Windows\CurrentVersion\IrisService /f && shutdown -r -t 0
  
• Used CMD >> DISM ScanHealth and RestoreHealth (no corruption detected)
  
• sfc /scannow
  
• Reinstalled the UWP using PowerShell: Get-AppxPackage -AllUsers | Foreach {Add-AppxPackage -DisableDevelopmentMode -Register “$ ($ _. InstallLocation) \ AppXManifest.xml”}
  
• Modified Registry: EnableXamlStartMenu under HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\Advanced - (set to 0)
  
• Deleted icon appcache under Users...Local
  
• Turned off Fast Startup
  

Going bonkers. I will try other external displays next, and maybe try my work USB display hub and see if anything changes. I feel like I tripped some weird bug.

The feature is called Taskbar preview and is not supposed to remain open after you remove the cursor from the icon. So it is working proper when it closes preview once the cursor is removed from the Taskbar icon.

EDIT: I have seen Taskbar preview stick and stay open before myself even after the cursor has been removed but that not suppose to happen and I don't know for sure why it happens in the first place but I'm guessing it has to do with memory running low .....
