This is been around for a while, is it just me or do other folks see it when running under the debugger (I am not testing the wxWidgets 3 configuration). In srcFFmpeg.cpp at or near line number 849, in the function:
bool FFmpegLibs::InitLibs(wxString libpath_format, bool WXUNUSED(showerr))
No, it only happens if you’re trying to use Audacity without/before installing (the optional) FFmpeg library. Given that “without” & “before” are certain to happen (especially for newbies), this code silently blows up in the Release configuration and that this is unnecessary (and probably superfluous now) debugging code - I contend that it should be removed.
