Topology Optimization: Status undetermined. A simulation error was detected.

Hello!

So I am trying to do an Topology Optimization, but I run into the following problem: 
As soon as I try to start an optimization (or an validation for that matter), it immediately stops and I get the following cryptic error message.
 

I have tried a new install, just a few days ago everything worked fine on my PC. What I do not understand is that the same simulation runs smoothly on my laptop, so it seems there is maybe a licence/install problem on my PC?

Thanks in advance for any help in resolving this problem.

Best regards, 
Franziska
