Error during run process

Does anyone know how to fix this error? "An exception occurred while running the after-startup-action." This error occurs every time I try to run my Mendix model. There are no errors in the error-list, but this error keeps returning. Picture can be found here:

Debug procedure can be:

Remove the after startup from the model settings and start it manually by creating an action button on an administration form. In some cases you get more information from the error if you do it this way.

Fix the problem and put it again in place.
