I'm doing some further testing on my end. It may indeed be that update, but I'm almost certain that it's not affecting most systems, which makes it even more difficult to pinpoint and fix. I'll do some further testing on the machines that I have.
Unfortunately, these are characteristically .NET crashes, which typically don't give me anything useful to go by to fix the issue. If it is what I think it is (a Windows or .NET glitch), sadly there may not be much I can do at all. I assume it's crashing to the desktop without any errors being reported on screen?
