Check the markings on your props (usually "A" or "B") and match them exactly to the diagram in your manual.

fibers or grass can wrap around the motor shaft under the propeller. Even a tiny amount of friction can prevent a motor from reaching the RPM necessary to "pitch" the drone forward.
With the drone off, spin each motor with your finger. Do they all feel equally smooth? If the motor that took the hit feels weird or stops sooner than the others, the shaft might be slightly bent.

Also, try sport mode. If it works, then it's the obstacle sensor.
