Debug wxWidgets Assertion Issue

I'm encountering an assertion issue we believe is with wxWidgets. Specifically, it's related to wxArrayString where it indicates an index out of bounds. This seems to happen during user interactions, but we can't pinpoint what specific interaction is causing it. Our app that uses wxwidgets is crashing for some unknown reason and we think this could be the reason.
The Freelancer that worked on this in the past for us is not longer a member here so looking for someone who can solve this issue for us.

Ideal freelancer would be someone proficient in wxWidgets, with strong debugging skills to help me solve this issue.
