I am having exactly the same problem (windows 11 latest update). I spend many hours deleting and cleaning all tracks of opera, folders and registries, but unfortunately nothing above 102 seems to work. I tried with 104 and 105 offline installers and they fail, some error related to pak corruption, uninstalling process also fails.
For now the only version that can be installed is 102 and auto update attempts also fail, after each relaunch it remains at 102.
