Can't use PythonCall in Custom System Image

Bắt đầu bằng cách tái hiện lỗi với lệnh PackageCompiler.create_sysimage được cung cấp và kiểm tra src/C/context.jl của PythonCall cùng với src/backend.jl của CondaPkg quanh các stack frame được báo cáo. Hoàn tất khi system image được tạo khởi chạy mà không gặp lỗi crash trong quá trình khởi tạo, đồng thời vẫn giữ nguyên thiết lập PythonCall và CondaPkg đã được báo cáo.

Affects: PythonCall

Describe the bug
I'm trying to build a Julia system image that uses PythonCall.jl. I can build the system image, but when I try to launch Julia with it it crashes on initialisation.

As a MWE, I've set up a package here that just uses PythonCall.jl. You can then run the following code to create a system image with this package:

using Pkg
Pkg.add(url = "https://github.com/BenCurran98/CondaIssue.jl")
Pkg.add("PackageCompiler.jl")
using PackageCompiler
create_sysimage(["CondaIssue"]; sysimage_path = "CondaSysImage.so")

This builds successfully, but when I run it I get the following error:

julia -JCondaSysImage.so --project=.

I've seen similar issues with system images posted here, but they seem more related to the python path rather than this error which I can't identify the cause of. I would appreciate any help you can offer! Thanks :)
