Critical UI Bug: Missing Navigation Bar & Address Bar globally after ExplorerPatcher usage

[sparco0]

Hello, I encountered a persistent issue with Windows 11 File Explorer after using ExplorerPatcher. The Navigation Bar (Address Bar, Back/Forward buttons) has completely disappeared. The Explorer window seems stuck in a broken legacy Ribbon mode.
Key details:
Scope: The issue is system-wide. It persists even on newly created User Accounts.
Troubleshooting attempted:
Reinstalled and uninstalled ExplorerPatcher (tried resetting to defaults).
Manually cleaned HKCU registry keys (BagMRU, StuckRects3).
Ran sfc /scannow and DISM (no corruptions found).
Verified that "Launch folder windows in a separate process" is disabled.
It seems like a global HKLM registry key or a shell extension registration was modified and not reverted properly. Could you advise which specific global keys control the visibility of the Navigation Bar/Ribbon UI? How i can fix this?

Please post windows version and build. You can find this by running winver. Please include if you are running x86-64 or Arm. And what language your windows is in.
Please post explorer patcher version, by running EP properties application and click on About on the left side.

Be careful with it though and I would check what each registry key does before you modify/delete it.

Thanks for trying to help. This method didn't work either.

You can download the current version of windows 11 from microsoft and do an in place install. It keeps all your personal files and applications, unless you tick the option to not keep them. I would still do a backup of your personal files before attempting this.
