The symptoms suggest one of your phase windings may be open circuit, either within the motor, in the wiring between motor and VFD or the VFD itself is bad.

Be sure to double check your wiring.  I have found the circuit diagrams/instructions provide with some three phase motors to be subject to misinterpretation.

Single Phase Induction motor (https://www.theengineeringprojects.com/2016/10/single-phase-induction-motor.html) needs a new winding. Does it has a single layer or double layer winding, may be you need to just change single layer.
