QT failed to load components
-
The app runs fine in QT Creator but when i try to use windeployqt, it doesn't run and shows nothing.
So i try to run the deployed version in my QT Creator and it throws these errors

Thanks for the suggestion. I've tried using the following:
windeployqt --qmldir <location of qml folder> <location of exe>Now the project runs but the GUI only shows the main windows, Other components are not showing
When i run the executable on the build machine, it works but on other machines it shows empty windows just as above
-
@pingal Do this: open a terminal, set QT_DEBUG_PLUGINS variable ("set QT_DEBUG_PLUGINS=1") and then start your app from that terminal. Check the output in the terminal (post it here). See https://doc.qt.io/qt-5/debug.html for details.
-
set QT_DEBUG_PLUGINS=1 myProj.exeIt executes the program but doesn't output anything on terminal (on both machines i.e. build and deployed)
The only difference is that on build machines, it shows buttons and other components but on other machines it just shows a blank window as posted in the above post
