  {{The reappearance of supernova Refsdal with detailed modeling of the lens
cluster allows us to measure the time-delay distance,}} which serves as a
powerful tool to determine the Hubble constant ($H_0$). We give a
cosmological-model-independent method to estimate $H_0$ through Gaussian
process regression, using time-delay measurements from this lensed supernova in
combination with supernova data from the Pantheon+ sample. {{Using eight mass
models for the lens cluster,}} we infer $H_0 = 64.2^{+4.4}_{-4.3} \,
\rm{km\,s^{-1}\,Mpc^{-1}}$ and using two cluster models most consistent with
the observations, we infer $H_0 = 66.3^{+3.8}_{-3.6} \,
\rm{km\,s^{-1}\,Mpc^{-1}}$. Our estimates of the value of $H_0$ are in
$1\sigma$ agreement with the results assuming a flat $\Lambda$CDM model and the
uncertainties are comparable. Our constraint results on $H_0$ from the eight
lens models and the two lens models indicate $2\sigma$ and $1.8\sigma$ tensions
with that estimated by Supernova H0 for the Equation of State, respectively.
However, our median values of $H_0$ from the two sets of lens models show good
consistency with $H_0$ inferred from Planck cosmic microwave background
observations assuming $\Lambda$CDM model within $1\sigma$. We also find that
our results for $H_0$ indicate $2\sigma$ deviations and $1.7\sigma$ deviations
from the constraint results of $H_0$ using six time-delay quasars by H0LiCOW
with the same analysis method.
