Fspy - Invalid vanishing point - What am I doing wrong?

Hi

I worked a lot with fspy last years but the last few times I get this error and I dont know whats wrong.

The two red lines are almost identical in angle, which doesn’t help when calculating the perspective. Try using 3-point perspective instead with 3 vanishing points, or move the red lines to be vertical instead, along the beams instead of being along the floor.
