Open the registry editor
(eg by pressing Windows + "R" and entering regedit)

Navigate to: HKEY_CURRENT_USER\Software\Classes

Right-click CLSID and select "Key" from the menu to create a new key.
Name this key {86ca1aa0-34aa-4e8b-a509-50c905bae2a2}

Right click the new key and select "Key" from the menu to create a
second new key inside the first, and name this InprocServer32

Expand InprocServer32 and double-click on "Default" in the right-hand pane.

In the resultant "Edit String" window, do not change anything and just
click on "OK".

Close the registry editor and reboot.

I don’t remember where I copied this from. Everytime I reinstall Windows 11 I go looking for this to make the context menu “normal” again.
