Hi @Tobias Richter ,
Have you tried repairing WebView2 Runtime? You can find it in App & features or Control Panel.
Also, as additional information, .69 was released on March 9, 2023, which was later than the day when this issue occurred. The latest 111.0.1661.41 has also been released. You can try migrating to the latest version.
