Many Git commands accept both tag and branch names, so creating this branch may cause unexpected behavior. Other customization options include custom working directories, command line arguments or a specific Julia environment (that is distinct from the active Julia environment in the VS Code window). I would suggest adding all the packages that arent your own code, like Plots, CUDA etc. to use Codespaces. Powered by Documenter.jl and the Julia Programming Language.
