Some days ago the tab completion (of Unicode chars) suddenly stopped working on VSCode.

I only have these plugins installed:

I have only recently started using VSCode. I don’t see any error message anywhere. Any idea what might be wrong?

I already removed and reinstalled the Julia plugin, and nothing.

Thank you.

edit: now I happened to open and close VSCode several times in a row, and I am getting this message:

Same issue here.  
(Thought mistakenly that it was due to the installation of some LaTeX extensions.)

Which version of Julia are you using? IIRC the latest stable release doesn’t work on ~~1.6.2 or~~ 1.7; insiders ~~supports the former and~~ will support the latter soon.

Edit: Actually, 1.2.7 and up should work fine with Julia 1.6.2.

Thanks for the explanation.  
(using julia Version 1.7.0-beta3.0, which is such a delight with the automatic missing packages installation N/[Y] feature, love it)

I’m using 1.6.1.

Is there anything I can do to get a meaningful error messages?

Go to `Outputs` \> `Julia Language Server` and report any error messages you might see there.

**Edit: I have installed Julia 1.6.2 and after all the packages got precompiled again, the LanguageSever is working.**

I have:

```julia
fatal: error thrown and no exception handler available.
InitError(mod=:IntelOpenMP_jll, error=ErrorException("Artifact "IntelOpenMP" was not installed correctly. Try `using Pkg; Pkg.instantiate()` to re-install all missing resources."))
error at ./error.jl:33
_artifact_str at /home/leandro/programs/julia/julia-1.6.1/share/julia/stdlib/v1.6/Artifacts/src/Artifacts.jl:551

```

just doing what the error tells me to do didn’t do anything. But I guess something is broken in some installation.

It may have something to do with: [https://github.com/julia-vscode/julia-vscode/issues/1990](https://github.com/julia-vscode/julia-vscode/issues/1990)

but removing MKL didn’t solve for me (deleting .julia is not an option exactly now).
