The top-level assembly will be open, Then I will open the sub-assembly within the top level assembly, then open a part and so forth. My issue is sometimes when i have several assemblies open and parts that out of no where Solid Works will just shut its self off. I will not get a crash report with no alerts when I reopen. I am running 2019 pro. Does anyone know why this is happening to me? This does not happen to my other colleagues. Thank you.
