P.S. I found a topic with a similar error in International section: here , but it didn't get any replies. I hope that won't be the case for this post.

Hi and welcome to devnet,

Something is not clear in your setup, do you have a proper cross-compilation setup ?
This usually means a Qt version for the host OS and a second cross-compiled Qt for your target.
It seems you have two distinct installation. One on your Windows machine and one in your WLS.
