Which OS do you have in your system.
Can you check which version of .NET framework do you have .
Creator needs .NET framework ver4.0 and above
I am using windows 10. I am also using .Net 4.6.2 (Latest).
So I have noticed that PSoC creator only crashes when I am using Visual Studio as well. I am not sure why that is but I think it is an indication that PSoC creator its self is fine.
I also experience the exact same problem, and I also only experience it while Visual Studio is open.
It is especially more irritable while I run a debug session with visual studio...
My coworkers and I (Five of us) have had this problem for the last 6 months. Drives us crazy!

Refer these threads to solve your issue.
This might also be .NET Framework version incompatibility issue. Go over to https://support.microsoft.com/en-in/help/2698555/microsoft-net-framework-repair-tool-is-available and use the Microsoft .NET Recovery tool.
If none of the above solves your issue, do let me know your system configurations and also check the memory usage when both Creator and Visual Studio are running simultaneously.
