I am using wxWebRequest to download a very small (1 KB) text file from the server with the following code:

auto WebRequest = wxWebSession::GetDefault().CreateRequest(this,
"https://www.pebytes.com/downloads/version.txt");
WebRequest.Start();

Bind(wxEVT_WEBREQUEST_STATE, &frmMacroLand::OnCheckNewVersion, this);

In Debug version all works well, but in Release version the application crashes and the event handler function is not even called:

void frmMacroLand::OnCheckNewVersion(wxWebRequestEvent &event)
{
    switch (event.GetState())
    {
        wxMessageBox(std::to_string(event.GetState()));

        case wxWebRequest::State_Completed:
        //rest of the code

Any ideas?

By the way, I am using Windows 11 with MSVC and wxWidgets 3.2
