cannot start the application from the terminal even after setting the path, showing QT error

I am trying to run an application from terminal but it is giving following error:

This application failed to start because it could not find or load the
Qt platform plugin “xcb” in “”.

Available platform plugins are: eglfs, linuxfb, minimal, minimalegl,
offscreen, vnc, xcb.

Reinstalling the application may fix this problem. Aborted (core

I have created the symbolic link and also added the path in the bash file but still I cannot run it from the terminal. Though if I am running it from the main directory, I can run it successfully.
Kindly suggest.
