Could be a faulty sensor or laser damage.

I also guess it was hit by laser.

Agree that this is most likely laser damage to the sensor.

If this is a mirrorless, realize that a weakness of the mirrorless design (or shooting a traditional DSLR in Liveview mode) leaves the sensor constantly exposed and subject to damage.  You have to use the same precautions with these that you would while shooting with a camcorder which also has its sensor constantly exposed.
