Method error during ⊑(::ConstsLattice)

[maleadt]

Reduced example:

(a(() = b{c} = d...) = 0)()

Internal error: encountered unexpected error in runtime:
MethodError(f=Core.Compiler.:(⊑), args=(Core.Compiler.JLTypeLattice(), Vararg{Any}, Type), world=0x00000000000015a5)

Bisected to #48063 (cc @Keno @aviatesk), so technically 1.10-only, but doesn't seem worth putting on the milestone.

A package started failing with pretty much this error; StructWalk.jl, https://s3.amazonaws.com/julialang-reports/nanosoldier/pkgeval/by_date/2023-09/17/StructWalk.primary.log. Looks like this issue isn't so theoretical after all.
