Not able to add step to Workflow

When trying to add a new step to an newly created workflow an Exception is thrown. When I save this workflow after this Exception was triggered I'm not able to open it again. However when not triggered I can activate it an reopen it.

I already tried naming my workflow differently, (thought I shouldn't be able to even create it if the name is already taken). I also tried other Entities with and without any customization from our side. I also used different Browsers (Chrome V64.0.3282.186, Firefox V58.0.2 and Firefox Nightly 61.0a1)

Does someone has an idea what could be wrong?

Here is also the Error Message
