The issue could be specific to your computer. I have Excel 2016 at home & Excel 2010 in the office. For what its worth, both systems are 64 bit. I have tried at both places and I am able to open the dialog with "This Worksheet" without any issues.Please find the attached desensitized file that crashes with Excel 2016 when selecting Conditional Formatting then Manage Rules then change Current Selection to This Worksheet. You won't need to select OK before the screen turns white and it crashes.
Nothing that raises alarm bells (at least for me and I am pretty lame in CF) in the applied ranges except they seem to be broken i.e. non-contiguous. It could be result of some deletion and addition of rows / cells.
If you've gotten rid of Excel 2016 then there's nothing that can be tested but if you still have it then it'd be good to implement Chihiro's suggestion.
- Clear CF from entire sheet. Save workbook.
- Rebuild it and then see if issue persists.
If you have 2016 on some other PC then possibly SirJB7's suggestion can also be tested.
