The problem has occurred in two different situations: 1. if during the simulation the runtime was not terminated properly, or was terminated with the task manager. -> In this case there was a damage in the project and I could only solve the problem by creating a new project and copying the data. 2. after the installation of foreign software on the same computer: -> Here I could solve the problem only in that I installed the TIA Portal again, without the foreign software. I hope this helps. Have a nice evening
