Citavi crashes with System.NullReferenceException

Citavi (Windows) is a very important software for academics and students. I created a wine bottle for it and installed different Net Franwework versions inside it since Citavi requires that. There was an improvement: Without the Framework installs, Citavi wouldn't install. Now it installs and even launches. However, upon launch, an error is produced and the app hangs loading. The error is:

Technical Information for the Citavi Team:
System.NullReferenceException: Object reference not set to an instance of an object.
   at SwissAcademic.Citavi.Shell.RegistryHelper.RegisterCustomUriScheme()

Any clue? I'm not a coder.
