Studio 2017 keeps crashing since the last SR1 update without warning or error messages - I suspect a division by 0

Studio 2017 keeps crashing since the last SR1 update without rhyme, reason, warning, or preceding error messages, which is seriously disrupting my workflow. I run Studio 2017 SR1 - 14.1.10014.38031 on Windows 7 with all the latest Windows, Java and .NET updates. Looking at the log files, I suspect a division by 0 in an internal process, because every single one of the log files ends like this:
