Cannot install CUDA.jl on WIndows.  
Is there a workaround for this?  
Should I try it with WSL or manualy download and install CUDA toolkit?

```julia
julia> using CUDA
julia> CUDA.versioninfo()

Hmm, it’s not matching against CUDA\_jll somehow:

What version of CUDA.jl? Can you try running with JULIA\_DEBUG=CUDA? Also, what driver version (`CUDA.version()`)?

Tried this in a new Julia terminal, and it worked without errors:

Maybe it was a network issue then during artifact download.
