PyFlow fails to Launch

[developeralgo8888]

i have conda environment with Qt 5.9.7 installed , PySide2 and all the PyFlow requirements but i get an error when i try to launch PyFlow. I have the LD_LIBRARY_PATH with the path to all libraries required. Is there something i am missing ?

qt.qpa.plugin: Could not load the Qt platform plugin "xcb" in "" even though it was found.
This application failed to start because no Qt platform plugin could be initialized. Reinstalling the application may fix this problem.

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