Qt app built for debug quits unexpectedly on Mac in Qt Creator

I have a somewhat simple program. Whenever I build and run for debug via Qt Creator, the app quits unexpectedly after clicking the log in button and a problem report is displayed with the attached content. However, the app should've simply displayed a message box. The same project works just fine under Ubuntu 22.04 and likewise versions of both Qt and Qt Creator.

As suggested by this topic on Qt Forum, the built app can be successfully run from the Terminal or Finder. In addition, it works perfectly in Qt Creator when built and ran for release.

Here's the link to the full project. Everything happens in login_window.cpp. You need argon2 installed in order to run the project. Or, try removing the dependency to see if you can reproduce the problem.
