Update: Applying the theory of modular forms, Wang and Yang have proved Conjectures 4.47 and 4.48.
They established two families of congruences modulo powers of 5 for the
Fourier coefficients of $(2E_2(2\tau)-E_2(\tau))\eta(2\tau)^{-1}$, where $E_2(\tau)$ is the
weight 2 Eisenstein series and $\eta(\tau)$ is the Dedekind eta function.
As consequences, they also obtained congruences modulo arbitrary powers of 5
for the $\mathrm{spt}$-type function $\mathrm{spt}_{C5}(n)$ introduced by Garvan and Jennings-Shaffer.
