I think I found out how to fix this. In the skyrim folder, there's a VCRedist folder. Open the .exe in that folder and it should ask you to repair or remove. Select remove and it might pop up third party software using the redist content. If it does say xyz software is using the content and it needs to be turned off then that third party software is most likely the cause of the problem. In my case, it was Razersynapse.exe and since I stopped that from running while I'm playing Skyrim, the pure virtual function call crash stopped. Continue uninstalling the redist and reinstall it. To my understanding, while skyrim is running, it is using tools from Microsoft to manage the pure virtual function but so is the third party software. Because of design flaws, the third party software ends up calling pure virtual functions from pointers that hasn't been wiped yet. This may also be the cause for other games having the pure virtual function call error. I know that this fix came late and a lot of people are enjoying FO4 atm but after I finally found out, I had to share.
