To help us solve the problem, could you provide the following information:
1. How did you obtain and install SyncroSim? Were there any email attachments involved (this uses Base64)?
2. Have you tried anything to fix the issue (e.g. reinstalling SyncroSim)?
3. What library are you using? Can you run multiprocessing with the most generic ST-Sim template library (Spatial Example)?
It would also be helpful to provide the run log that contains the error message. Thanks!
