An error occurs when I use ImGuiTextFilter in a package

I found that when I use ImGuiTextFilter in a package, there are some issues, but it works well when I run codes with "include". Is there any way to solve this problem? I wrote some sample codes and recorded the error message as follows. Codes inside the rendering loop:

let 
    filter::Ptr{ImGuiTextFilter} = ImGuiTextFilter_ImGuiTextFilter(C_NULL)
    content = ["ajfa;", "qoe;asdjk", "xnm,d", "178250kd", "g078gyu", "awefr23"]
    global function filterbug()
        CImGui.Begin("TestBugs")
        ImGuiTextFilter_Draw(filter, "Filter contents", 16CImGui.GetFontSize())
        for s in content
            ImGuiTextFilter_PassFilter(filter, pointer(s), C_NULL) || continue
            CImGui.Text(s)
        end
        CImGui.End()
    end
end

I wrote it in a package named TestBugs with rendering function UI. when I run it through:

include("src/TestBugs.jl")
TestBugs.UI()

it works well. But when I run it through:

using Pkg; Pkg.activate(".")
using TestBugs
UI()

it will produce an error

Please submit a bug report with steps to reproduce this fault, and any error messages that follow (in their entirety). Thanks.
