Theres no error,
How do you know? I don't see any error handling in your code. Print https://doc.qt.io/qt-5/qsqldatabase.html#lastError in the else block

But before that do this: set QT_DEBUG_PLUGINS environment variable to 1 before starting your app and then post its output here. -

Hi,
The plugin is currently not pre-built anymore as Oracle changed their licensing with regards to MySQL so you'll have to build it yourself.

Go to @jsulm's link again and scroll down. There is a section called "How to Build the QMYSQL Plugin on Windows" -- it contains instructions on how to build the DLL.
