I got failed execute when I try to run this tool although it took several minutes then I tried to use the repair geometry tool and tried count tool again but still failed and got invalid topology so what should I do ?

Would you be able to share the data so we can investigate?

I got the data from this link when I’ve tried to do this tutorial. The last time my laptop got freeze after took like 30 minutes to run this tool.

If I follow the tutorial and select Month = 9, which selects 43 features, and then run CountOverlap it works as expected, and fairly quickly.

However, if I do not perform a selection and try to run CountOverlap on the entire data set it will cause an out of memory failure (which may hang your machine) due to the massive amount of overlap in the entire dataset. It even ran out of memory on my machine with 256GB of RAM. I'd guess that the original tutorial authors did not intend you to run on the entire dataset.
