Steam Crashes before Games List can populate

I love my arcade machine, I paid for a lifetime membership. I love the community and I have solved all my problems by myself ..... up until now. I apoligise but help would be appreciated. GameEx crashes when I click the link to my steam games. I can see the list of games starting to scroll in from the left, but it freezes and I am shown  the following error log. Please any direction for ideas would be appreciated.

 The error log is attached.
