Application failed to start because it could not find or load the Qt platform plugin "xcb" in

Question

I am using Qtcreator to build and run my program. Build is success but while running I am getting the following error

This application failed to start because it could not find or load the Qt platform plugin "xcb"
Reinstalling the application may fix this problem.

I am using Qt5.6.1-1 and creator 4.0.3 based on Qt 5.6.1

Tried by exporting path
export QT_PLUGIN_PATH=/home/SysUser/Development/Qt5.6.1-1/plugins/platforms Still its not working

I am having Qt5.12.6 also installed but this app need Qt 5.6.1 so I renamed Qt5.12.6 folder.

Any lights will be a great help

What do you mean by "so I renamed Qt5.12.6 folder"? Renamed it from "Qt5.12.6" to "Qt5.6.1"? — Christian Halaszovich, Jun 27 '22 at 08:19
This might help: "To obtain diagnostic information from Qt, about each plugin it tries to load, use the QT_DEBUG_PLUGINS environment variable. Set this variable to a non-zero value in the environment where your application is launched." https://doc.qt.io/qt-5/deployment-plugins.html — HiFile.app - best file manager, Jun 27 '22 at 08:23
@ChristianHalaszovich That would be crazy. I do not think he did this... :) — HiFile.app - best file manager, Jun 27 '22 at 08:24
I renamed Qt5.12.6 to Qt5.12.6_Temp and used Qt5.6.1 which is already installed — Sijith, Jun 27 '22 at 08:46
I think the path should be `export QT_PLUGIN_PATH=/home/SysUser/Development/Qt5.6.1-1/plugins`, isnt it? — Peter Lee, Jun 27 '22 at 09:58
Yes Peter I gave the same path through terminal then launched Qtcreatur usign same terminal — Sijith, Jun 27 '22 at 10:39
@HiFilethebestfilemanager Well, I've seen people do things like this (and worse) ;-) — Christian Halaszovich, Jun 27 '22 at 12:07
