I have removed the `.julia` directory and used `Pkg` package manager to install `PyPlot` only in Julia 1.6.3 on a Windows machine. `qt.qpa.plugin` returns an error.

```julia
julia> versioninfo()
Julia Version 1.6.3

Platform Info:
  OS: Windows (x86_64-w64-mingw32)

julia> plot([1,2,3])
qt.qpa.plugin: Could not load the Qt platform plugin "windows" 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: direct2d, minimal, offscreen, windows, webgl.

(@v1.6) pkg> st
      Status `C:\Users\nmr\.julia\environments\v1.6\Project.toml`
  [d330b81b] PyPlot v2.10.0

```

The solution proposed in [python - How to fix "could not find or load the Qt platform plugin windows" while using Matplotlib in PyCharm - Stack Overflow](https://stackoverflow.com/questions/41994485/how-to-fix-could-not-find-or-load-the-qt-platform-plugin-windows-while-using-m) with `QT_PLUGIN_PATH` set to `.julia\conda\3\Library\plugins` does not seem to work.

Has anyone already seen it?
