ERROR: Failed to precompile LinearSolve about linearsolve.jl

[cwittens]

The folder C:\Users\colli\.julia\artifacts\6288063f1c2040dd23c7710d999838037ec279a5\ did exist but it was empty.
What I did is I deleted the folder and tried to use LinearSolve and I took some time, but now it is working just fine.
Thank you!

It looks like something happened with the MKL artifact. Did you try rebuilding? Is this a standard binary from https://julialang.org/downloads/ ?

[cwittens]

Yes it is the standard binary.

@cwittens can you please confirm whether you have the file C:\Users\colli\.julia\artifacts\6288063f1c2040dd23c7710d999838037ec279a5\bin\mkl_core.2.dll on disk? If so, can you try to debug it following the example at JuliaPackaging/Yggdrasil#7508 (comment)? At least that should point out to what library is missing. I'm not familiar with Windows at all, so don't ask me much more than what I linked already 🙂
