So the main part of the error is:

Error System.ArgumentException: Das Objekt mit dem Typ "System.Boolean" kann nicht in den Typ "System.String" konvertiert werden.
Error System.ArgumentException: The object with the type "System.Boolean" cannot be converted into the type "System.String".​

Are you using any mapping components?

Can you run the app in debug and see where it crashes?

What exception handling do you have? Is it in each model/embedded model or just the global one?

Dear Alex,
yes i use a lot of mapping components, i checked all and didnt find the error. Debugging is not easy, because it needs a lot of input data.
i put exepition Trigger for all components in project, but dont get an other error than the explained error above. can i reset the project an delete all of Data from it?
maybe the errors comes from old Data in the Process?
any other idea

Could you create a feeder form to give you an easier way to setup/pass test data to the process?

Have you just ticked the exception to log or are you adding the exception details to a log entry component?

Has it only just started to happen? Does it happen in Dev and Live?

i think i can not add a feeder form in a WorkflowProject. or is there a way for it.

After your Reply a added a log entry Component too, but get no additional error in the logs. I added also in all embedded Models, everywhere but no additional logs. the trigger component brings no error.

this project is only at dev stage, no production stage at this time.

I think the error does'nt come from the components of the Project. I checked all of it. and the Project works like it should. All functions are working like developed.

from where this error comes? i dont find out the model where it happens

Hi Alex, I Have now more information:
i deleted all DatabaseData from the Project, i deleted the Project from IIS and published again the project. 
nevertheless the error comes back immdeatly after i restart der workflow server service. i dont understand this, because there is no data in the process.
maybe there is data from in the data store in filesystem. i dont think so, that any model or component has an error. it must be any simple configuration
