Hello onboardx! 

It is possible that it is the issue described in the FAQ. It is noted that the crash occurs at the moment of compiling due to the latest updates from Microsoft. To solve it, as I've read, you need to contact Siemens Technical Support so they can provide you with a patch. I'll leave you the link to the FAQ below.

I installed SP2 into V19 but the problem still continues.

Have you contacted Siemens Support? They are the ones who have to send you the patch. I don't know if it will be the same problem described in the FAQ, but write to them so they can help you with the crash.
