Please help!!

If you looked through this forum you would see "hundreds" of other posts on this topic. They all tell you to start by setting environment variable QT_DEBUG_PLUGINS to 1 and then running your Qt application. Look at the diagnostic output you will get.

You want @JonB to search for you? You can't do it on your own?

@Bonty
There isn't any one solution. There are multiple possibilities depending on the diagnostic output. Start by setting that environment variable and looking at it, especially right near the end where it should indicate what your situation is.
