"Unexpected exception when initializing the view part Bericht" - Studio not starting any more

Hi there,

I keep getting the error message "Unexpected exception when initializing the view part Bericht" - I can't even open Studio any more. It happened for the first time when I tried to access the report of a project, nothing special about it.

I didn't install any add-ons lately, only did an update the other day and a number of Repair installations because Studio started to throw error messages out of nowhere.

Does anyone have an idea what could be done?.

Thanks, Birgitt
