qt.qpa.plugin: Could not load the Qt platform plugin "xcb" in "" even though it was found, debian 9

I'm getting

 qt.qpa.plugin: Could not load the Qt platform plugin "xcb" in "" even though it was found.

after a fresh installation of qt creator in Debian 9. Unfortunately, the solutions here tell me to do ldd /usr/lib/qt/plugins/platforms/libqxcb.so but /usr/lib/qt/ doesn't even exist.

Hi
How did you install Qt ?
When using the online installer you can choose the install dir.

Did you try locate libqxcb.so to see if its somewhere else?

Also just to be clear. This errors come when running via Creator ?
Not trying to run .exe alone. Correct ?
