Python crashing on mac os X 10.15.5

Python is crashing with a message of the form below when using Streamlit (always Thread 6 crushes)

I tried reinstalling pandas. That did not work.

Here are the details from the message (to fit the message in this post, I removed some of the details from the threads that did not crush and the Binary Images information):
