I encountered that FlexSim automatically shut down when running A*start. most serious one of them is not able to save file, then can not re-open file successfully, always remaining loading file. hopefully, to get some helps here.
A*star module problem
FlexSim 22.2.0
How big is your grid? You may be reaching resource limits of your system.
Hi Jason, not resource limits because I have license. the error prompt is as picture. 
This error message happens as FlexSim tries to load the model file. It looks like the model file is corrupted, so that FlexSim cannot load it.
@Jason Lightfoot 's question is not about license limits, but about how much RAM your computer has. If you make an AStar grid very large, the FlexSim model might take up too much RAM, and that eventually, FlexSim crashes because of this.
Could you upload an example model to the file sharing link above? That may help us diagnose the issue.
