I can indeed see the difference in dispatch between the different methods, but were they not supported at the start?

julia> Matrix{<:BigFloat} <: Matrix{<:AbstractFloat}
true

Indeed, that's the issue at hand. The problem lies in the fact that this method errors when dealing with BigFloats because the inv! operation is not supported for BigFloats.

To address this issue, this pull request (PR) eliminates the dispatch for BigFloats since BlasFloat does not include BigFloats. Consequently, BigFloats will no longer utilize this specific method but will instead use a more generic version.

Makes total sense now.
