Electronics engineer help. H bridge motor controller circuit. Relays are fluttering when motor load applied.

My project is about troubleshooting an H-bridge motor controller circuit with an dc motor that is fluttering the rekays when a load is applied. The voltage of the motor is 24V, and I have a schematic available. I need someone experienced in electronics engineering to help me test and troubleshoot the circuit, and I will provide a voltmeter for them to use.
