Tire deformed after tube replacement.

Looks like the tyre bead isn’t seated properly, try pumping it up to maximum pressure, usually around 55psi, you should hear it pop onto the rim. You can bounce it on the floor a little to encourage it, and then deflate back to normal riding pressure. If that doesn’t work then try deflating it entirely and putting a bit of washing up soap on the inner lip of the rim to help the tyre slide itself into place before repeating the max pressure process.
