julia error: method too new to be called from this world context

I want to execute the function of the module (denoted daughter) by executing another module (denoted mother). To do that, I wrote down code as follows in the mother:

include("User/initialization/Background.jl") initialization.Background() #1 

However, the daughter didn't work because of the following error: MethodError: no method matching Background() The applicable method may be too new: running in world age 32734, while current world is 32738. Closest candidates are: Background() at C:\Windows\Application Data\User\initialization\Background.jl:7 (method too new to be called from this world context.)

Edit

module Hi using DelimitedFiles function Hi_Hello() if Command[1,1]==1 include("User/initialization/Background.jl") initialization.Background() #1 else end end end using .Hi Hi.Hi_Hello 

module initialization using Plots, DelimitedFiles, BSplineKit function Background() writedlm("Background.txt", data_BG) end end using .initialization initialization.Background 

It is executing using VScode and initialization(module) included in the directory:("User/initialization). when I command on the terminal, it works. include("User/initialization/Background.jl") initialization.Background() #1 but when I command through executing function, it didn't with error as I mentioned original post. MethodError: no method matching Background() The applicable method may be too new: running in world age 32734, while current world is 32738. Closest candidates are: Background() at C:\Windows\Application Data\User\initialization\Background.jl:7 (method too new to be called from this world context.)
