  In this paper, we study quantum gravity effect on the symmergent black hole
which is derived from quadratic-curvature gravity. To do so, we use the
Klein-Gordon equation which is modified by generalized uncertainty principle
(GUP). After solving the field equations, we examine the symmergent black
hole's tunneling and Hawking temperature. We explore the graphs of the
temperature through the outer horizon to check the GUP influenced conditions of
symmergent black hole stability. We also explain how symmergent black holes
behave physically when influenced by quantum gravity. The impacts of thermal
fluctuations on the thermodynamics of a symmergent black holes spacetime are
examined. We first evaluate the model under consideration's thermodynamic
properties, such as its Hawking temperature, angular velocity, entropy, and
electric potential. We evaluate the logarithmic correction terms for entropy
around the equilibrium state in order to examine the impacts of thermal
fluctuations. In the presence of these correction terms, we also examine the
viability of the first law of thermodynamics. Finally, we evaluate the system's
stability using the Hessian matrix and heat capacity. It is determined that a
stable model is generated by logarithmic corrections arising from thermal
fluctuations.
