Julia VSCode extension crash upon unpacking an alias

[DaniGlez]

Hi, I understand this issue belongs here; let me know if it should go in a different repo. Here's a MWE:

struct Foo
    a::Int
    b::Int
end

const FOO = Foo

function bar(x)
    (; a, b) = FOO(x, 2x)
    a + b
end

The LS will crash at the (; a, b) = FOO(x, 2x) line, here's a stacktrace:
