why the solid works crashes while working with it?

I used to have the same problem
is it a desktop or laptop?
does it have proper air circulation,
can your device handle the workload?
whats your set up?
my laptop used to always crash but i just upgraded the RAM and only used it on an empty desk, that pretty much sorted it for me.

Have you tried updating your computer? Check for windows updates. I had the same problem so I just restarted my computer in safe mode and ran it. Also it could be a glitch in the installation just try uninstalling anmd reinstalling. Hope this helps.

I ALREADY FACE THIS PROBLEM THERE IS NO SOLUTION FOR IT SOLID WORK CAN'T HANDLE BIG FILES

-Graphic card drivers not updated (or not a suitable graphic card)
-To big assemblys
-lag of RAM
-somtimes re-instaling solid works helps aswell (it worked for quit a few of my class mates)
