I’m having this issue in VSCode, not sure exactly what is going on, I am quite clueless.

Might be this bug: REPLExt: no method matching repl_init(::REPL.LineEditREPL) when loading packages in REPL mode. · Issue #56216 · JuliaLang/julia · GitHub

If you are a beginner, I would stick with Julia 1.10 for now, 1.11 still has some bugs that need to be ironed out.

juliaup add 1.10
juliaup default 1.10

Thanks, can’t recall exactly how but I’ve fixed the issue now.

For others running into this (as I did today):
Running import Pkg in a separate Julia repl fixed it for me.

I run into the same error with fresh empty 1.11 environment. Adding any package in a separate repl fixed the problem.
