Dreame X50 Ultra wont clean

Everytime it is supposed to clean, whether I tell it to start, or during its scheduled cleaning, it leaves the base and then just stops and says that it is blocked by an obstacle when there is nothing around it. I have cleaned the sensors and don’t know what else to do.

I factory reset it the first time it happened, and the second time I set up the robot, it worked for a week, then the error started again.
