Butterfly error(with window)

I’m currently analyzing wind with a butterfly. However, when I changed the number of glob refines in the snap hex mesh during the process, the programming took a long time, so I checked the next day, and the computer was turned off and turned on. So when I turned it on again, it was confirmed that the windowerorr. What should be the specifications of the computer and how should I solve these problems? And the same error is confirmed in the load mesh.
