There’s an issue
Circular dependency on 1.10 · Issue #573 · SciML/LinearSolve.jl
I don’t know how to read that cycle warning, not sure if it’s even legit. Maybe someone can help explain. I did check that there’s a RecursiveArrayToolsSparseArraysExt.jl, and SparseArrays is weirdly a full dependency of LinearSolve, not among [weakdeps].
