Automatic julia installation fails with "app is damanged and can't be opened"

[biona001]

On mac with M1 CPUs, I tried the following

install.packages("JuliaCall", repos='http://cran.us.r-project.org')
library(JuliaCall)
julia_setup(installJulia = TRUE)

which downloads Julia 1.9 but immediately pops a warning that the downloaded app is damaged and can't be opened:

The full error message is as follows:

• Julia works if I manually download it from https://julialang-s3.julialang.org/bin/mac/aarch64/1.9/julia-1.9.0-macaarch64.dmg
• I'm trying to write an R package that wraps a Julia package, and ideally, it would be nice if R users don't have to worry about installing Julia.

Any tips would be appreciated.

It could well be this problem:

The suggested solution didn't work...

@Non-Contradiction Is it true that, for now, if I want to write an R wrapper for my Julia package, I must recommend users to install Julia first?
