Any solutions to this yet? I am going through a similar issue

Any solution to this issue yet? I am using xcode 12.4 on mac os catalina.

Thank you for your response Claude31. Some hint: open the Storyboard as html search for object that fails see if you find anything suspicious (by comparing to a similar object that works). Sorry if this seems like a stupid question, but how do I check for objects that fail once i open the Storyboard in a text editor? I did try going over it but it is massive, there is no way I could ever check it manually.
