I believe the only viable timeline is the one where time travel is never invented because if you create the machine to go back to prevent something happening then there is no need to create the time machine.
Which yes is an actual paradox
That's why the reason for inventing the time machine is "just in case"
Unless the time machines end up being restricted in travel only to the times after they're built. Which would resolve the paradox
Ex: The movie Primer. A good time-travel idea in a bad movie.
A great movie.
Basically everytime you go back it will make changes to the future in such way you don't exist thus the time machine by its very nature can never be discovered. Everyone that does immediately erases their future self from existence.
I've never been motivated to create a time machine, but you've suddenly made it extremely appealing...
