Could he just run it the first time play for 5 minutes then exit and then go back in (point of contention) - then alt tab out unless it crashes either way he can check windows + R type in eventvwr and see if something throws red flag icon (red triangle with exclamation point) this would indicate the corrupt file. If it is a corrupt file - likely on his own end as lspdfr is working for all of us just fine - he may need to reconcile it. If there is none then issue could be software side but it is highly unlikely. Just a thought. @akcasoft it is the most sound way to diagnose in the beginning. However, be very careful of what you reconcile and disclaimer for me: this is just another way to detect issues however from your first post i would assume you aren't very tech savvy (maybe you are) so I would only do it if you feel comfortable doing so. I have zero liability if you do this.
