Crash on pygui(:wx) or pyimport("wx") using PyCall.

[FredK712]

With these packages:
(@v1.4) pkg> status
Status C:\Users\Fred\.julia\environments\v1.4\Project.toml
[8f4d0f93] Conda v1.4.1
[438e738] PyCall v1.91.4
[d330b81b] PyPlot v2.9.0

With everything installed in the default locations, when using the Conda local python version 3.7 and Conda installed wxPython, if I attempt either of the commands in the title, Julia halts with the crash dump below. "pygui(:qt)" works OK.

If I change line 405 of PyCall.jl from "@static if Sys.iswindows()" to "@static if false #Sys.iswindows()" to bypass the activation context stuff which wxpython classic does on its own (https://github.com/wxWidgets/wxPython-Classic/blob/master/src/helpers.cpp) and wxpython - Phoenix doesn't appear to need, then:
julia> Pkg.add("PyCall")
julia> using PyCall
julia> pyimport("wx")
julia> pygui(:wx)
both commands work without crashing.

Can you try with the recent stable releases if this is still an issue? Works fine on mac, but it may only be a problem on windows.

Hi Viral, It works fine on my Intel Mac (macOS Monterey) in the latest version of Julia. I’m nut using Windows so I can’t check it there. Thank-you!

Let's close and reopen if someone finds otherwise.
