$\begingroup$ Plain hydrogen fusion isn't like deuterium or deuterium-tritium fusion. The fusion reaction inside the Sun runs very slowly, it's not like a bomb. The power density in the Sun's core per unit volume is comparable to that of a compost heap. Per unit mass it's even worse. See physics.stackexchange.com/q/370899/123208 & physics.stackexchange.com/a/540199/123208 $\endgroup$

$\begingroup$ The pressure in the core is still extremely high, though. $\endgroup$

$\begingroup$ That's true, and so is the density. But that's mostly due to the gravity rather than the fusion. And it's tiny compared to the density needed to achieve a black hole for even a solar mass. The density needed for a smaller mass is much greater. $\endgroup$

$\begingroup$ Blackhole requires sufficient mass which our Star(Sun) does not have(Not enough Gravitational pull), even if it's fusion stops ie. it runs out of fuel which will cause it to be a white dwarf. (Lowkey wanted to add mass to the sun at first but then realized if we do achieve such technologies we might as well make our own star and force it to collapse rather than bullying the sun) $\endgroup$
