The last stars will burn out in 120 trillion years
We think. We still haven’t solved things like the dark matter/energy problem. The answer to that alone could drastically change what we estimate will happen in the distant future.
Stuff only burns for so long. We might learn more about the geometry of space and that there is more out there at greater distances where maybe even other Big bangs are possible but there is a certain maximum amount of time that a star can exist.
Over the time scales of the life of a proton the maximum variability in the amount of time a star can burn is a rounding error against the scale of numbers needed to express the amount of time it takes for hawking radiation to reduce black holes to ultra long wavelengths of infrared radiation.
