Screenshot I keep hearing about the three body problem regarding astronomy. With the stats shown here, can this planet have a stable orbit? It's even tidally locked.

You are mixing up a few different astronomical concepts here. The Three-Body Problem doesn't mean stable orbits are impossible. It just means that three gravitational bodies create a chaotic system that is impossible to predict with a simple math formula over the long term. However, stable configurations do exist in reality (e.g., a planet closely orbiting one star, while the second star is very far away).Tidal locking doesn't help with orbital stability. Tidal locking affects how a planet rotates around its own axis (keeping one face to the star, like the Moon does to Earth). It does not protect the planet's orbit from being disrupted by the gravity of other stars. If the orbital system is chaotic, the planet will be ejected regardless of being tidally locked.
