upgrading from v2.16 to v2.17 causes `ERROR: expected tuple type`

[nsajko]

On v2.17.1 I often get an error like this when trying to use ascend:

julia> ascend(only(invalidation_trees(raw_invalidations)).mt_backedges[11][end])

The specific reproducer is this, followed by the command above:

using SnoopCompileCore: @snoop_invalidations
raw_invalidations::Vector{Any} = @snoop_invalidations begin
    struct I <: Integer end
    function Base.Int(::I) end
