Executing the tests completely manually makes no problems...

There must be any different settings/configs if the tests are started with Jenkins, maybe you can try out different settings/configs?
Stopping Ranorex Test execution on the PC via "Break", then the PC crashed
What did you mean with "Break", the normal "Pause/Break" key?
Can you also send us some more information about your test environment and your application under test?
Maybe you can also send us a Ranorex Snapshot file of your application?
will show you how to generate a snapshot file.
