Whenever I open assembly in SolidWorks 2017, no matter the size, if I try to change a dimension of a part within the assembly, I get the error message 'a problem has caused the program to stop working correctly' and am forced to close the program. This only happens in assemblies, I can play around with individual parts as I please.

I've tried restarting my machine (multiple times), running from SolidWorks rx, repairing my install and completely reinstalling SolidWorks. I have been running the program on this computer with no problems for the past eight months with no problems, and this started in the last 12 hours.

Any ideas??
