Ffprobe Error When Analyzing Videos DLC 2.2b6

I was attempting to analyze a video set after training and evaluating the network using DLC 2.2b6 (latest version). When I attempted to analyze the videos, I receive the following error message:

I did see on other forum posts that updating to the newest version of DLC would resolve the issue. However, this did not work for us as the error occurred while using v. 2.2b6. Thanks!

I want to add that the version of wxpython being used is v.4.0.7.post2
