We discuss a novel UV completion of a class of Argyres-Douglas (AD) theories in the Ω-background by its embedding into the renormalisation group flow from five dimensional \( \mathcal{N}=1 \) superconformal field theories (SCFT) on S1. This is obtained via analysing these theories in the light of (q-)Painlevé/gauge theory correspondence, which allows to compute the five dimensional BPS partition functions as an expansion in the Wilson loop vev with integer q-polynomials coefficients. These are derived formulating the gauge theory on a blown-up geometry and using a five-dimensional lift of (topological) operator/state correspondence. We discuss in detail the phase diagram of the four dimensional limits, pinpointing the special AD loci. Explicit computations are reported for \( {\overset{\sim }{E}}_1 \) SCFT and its limit to H0 = (A1, A2) AD theory.
