It has been pointed out on maths forums that Godels use of the axiom
of reducibility makes his incompleteness theorem invalid
see

the university of california maths depart notes godels system p uses
AR

The system P of footnote 48a is Godel’s
streamlined version of Russell’s theory of types built on the natural
numbers
as individuals, the system used in [1931]. The last sentence of the
footnote
callstomindtheotherreferencetosettheoryinthatpaper; KurtGodel[1931,
p. 178] wrote of his comprehension axiom IV, foreshadowing his
approach to set theory, “This axiom plays the role of [Russell’s]
axiom of reducibility (the comprehension axiom of set theory).”
now
The stanford encyclopedia of philosophy ststes

many critics concluded that the axiom of reducibility was simply too
ad hoc to be justified philosophically.
Ramsay states like wise about AR
its introduction into mathematics is inexusable.
Such an axiom has no place in mathematics,
.. (THE FOUNDATIONS OF MATHEMATICS* (1925) by F. P. RAMSEY
Even the editors of godels collected works note
From Kurt Godels collected works vol 3 p.119

“the axiom of reducibility is generally regarded as the grossest
philosophical expediency “
Now as i showed godels uses AR in his system P to prove his
incompleteness theorem
but
as we also see that axiom is not regarded as valid
thus by useing an invalid axiom godels incompleteness theorem must
like be invalid-even if others have proven by other means an
incompleteness theorem
it remains that WHAT GODEL DID is invalid
Now it has been pointed out that
The systems to which we apply Godel's theorem nowadays
DON'T EVEN NEED an "axiom of reducibility
but my point is
It is what godel did and what he did was use AR -thus making HIS
incompleteness theorem invalid
