OneDrive desktop client does not start after complete uninstall, cleanup and reinstall

Hello,

I have a problem with the OneDrive desktop client on Windows 11.

Issue

The OneDrive desktop client does not start at all.

• OneDrive.exe exists in: C:\Program Files\Microsoft OneDrive\OneDrive.exe
• Double-clicking OneDrive.exe does nothing.
• No sign-in window appears.
• No OneDrive cloud icon appears in the system tray.
• No error message is shown.
• Running: "C:\Program Files\Microsoft OneDrive\OneDrive.exe" /verbose returns immediately with exit code 0.
• Running: "C:\Program Files\Microsoft OneDrive\OneDrive.exe" /? also produces no output.

What I already tested

• DISM completed successfully.
• SFC completed successfully.
• OneDrive was uninstalled.
• Remaining OneDrive program folders were deleted.
• Local OneDrive configuration folders were removed/renamed.
• OneDrive registry entries were cleaned.
• Old account configuration was removed.
• A previously connected work/school account was removed from Windows.
• OneDrive was installed again from the latest installer.
• The issue remains exactly the same.

Additional findings

• The file OneDrive.exe is present after installation.
• The modern OneDrive Photos (Beta) app starts normally.
• The classic OneDrive synchronization client does not start.
• Searching for "OneDrive" in the Start menu only shows the OneDrive app, not the classic desktop client.
• In some cases only a "OneDrive Sync Service" process appears in Task Manager.
• No useful OneDrive application errors are logged in Event Viewer.

Important test

I created a completely new local Windows test user account.

The problem occurs there as well:

• OneDrive.exe does not start.
• No sign-in window appears.
• No cloud icon appears.

Therefore the issue does not appear to be limited to my original Windows user profile.

Data status

My local data is still intact on a separate drive:

E:\OneDrive

The problem only affects launching the OneDrive desktop client.

Could you help investigate why the OneDrive desktop application exits immediately without showing any UI or sign-in experience?

Thank you.
