You say Godel's statement that is unprovable, is unprovable because it is an epistimalogical antinomy, when it isn't.

It is a statement about the non-existance of a number that satisfies a particular property, which will be a truth bearing statement (The number must either exist or it doesn't)

Well, Godel wasn't talking about "undecidability", but incompletenwss, which is what the WORDS you used talked about. (Read what you said above).

When we create a three-valued logic system that has these
three values: {True, False, Nonsense}
https://en.wikipedia.org/wiki/Three-valued_logic
IF you want to work with a Three Value logic system, then DO SO.
But, remember, once you make you system 3-values, you immediately loose the ability to reference to anything proved in the classical two-value
>
Then "This sentence is not true" has the semantic value of {Nonsense}
This sentence is not true: "This sentence is not true" has the semantic
value of {True}.

Although it may be difficult to understand that is exactly the
difference between Tarski's "theory" and "metatheory" simplified
as much as possible.
And, once you add that third value to logic, you can't USE Tarski, or even talk about what he did, as it is OUTSIDE your frame of logic.
For teaching purposes it is easier to think of it as
a third semantic value. In actuality it would be
rejected as invalid input.

This is Tarski's Liar Paradox basis

That he refers to in this paragraph of his actual proof
"In accordance with the first part of Th. I we can obtain
the negation of one of the sentences in condition (α) of
convention T of § 3 as a consequence of the definition of
the symbol 'Pr' (provided we replace 'Tr' in this convention
by 'Pr')." https://liarparadox.org/Tarski_275_276.pdf

Allows his original formalized Liar Paradox:

x ∉ True if and only if p
where the symbol 'p' represents the whole sentence x
Right, He shows that this statement is EXPRESSABLE in the meta-theory (something I don't think you understand)
I do. I understand it better than most.
This sentence is not true: "This sentence is not true" is true.

to be reverse-engineered from Line(1) of his actual proof:
(I changed his abbreviations of "Pr" and "Tr" into words)
Note, "Th I" was established without reference to the meaning of the class.

Here is the Tarski Undefinability Theorem proof
(1) x ∉ Provable if and only if p // assumption
NOT ASSUMPTION, he has shown that such an x must exist in the theory (if it meets the requirements)
That is an adaptation of his Liar Paradox: x ∉ Tarski if and only if p
(2) x ∈ True if and only if p // assumption
NOT ASSUMPTION, but from the DEFINITION of what Truth is, the statement x is true if and only if it is true (since p is the whole statement x)
Convention T
(3) x ∉ Provable if and only if x ∈ True. // derived from (1) and (2)
(4) either x ∉ True or x̄ ∉ True; // axiom: True(x) ∨ ~True(~x)
(5) if x ∈ Provable, then x ∈ True; // axiom: Provable(x) → True(x)
(6) if x̄ ∈ Provable, then x̄ ∈ True; // axiom: Provable(~x) → True(~x)
(7) x ∈ True
(8) x ∉ Provable
(9) x̄ ∉ Provable

Right.
Thus proving that there exists and x where x must be true, and x must be unprovable.
You just don't understand what an "assumption" is and what is an application of a proven statement.
Tarski assumes the Liar Paradox and finds out that this
assumption does not work out.
