Hey Chris,
Pure virtual function call can be almost anything. It is sometimes caused by changes in the catalog database when opening a file that was created in an older version. It can be caused by out of date video card drivers or by corrupted or incomplete versions of Microsoft’s C++ (2020 uses the C++2010). Sometimes a copy/paste of the design to a new file will resolve it. Sometimes simply resetting the registries resolves it. Sometimes the C++ needs to be uninstalled and reinstalled and sometimes it is a matter of updating the drivers for your video card. I have found the most success with the video card drivers.
The live chat for support is an ongoing issue. We are currently with one provider but working to switch to another and things have been in limbo for a while now. The best way to get through to support is still the phone and email.
Neil
