Multicast Troubleshooting

Hi, I am completely new to Multicast troubleshooting, I am aware of what Multicast is and how it works but I am having an issue troubleshooting multicast. I have 2 windows machines on VLAN 95, that communicate over the 239.0.38.0/24 multicast range. Their non multicast IPs are 10.99.1.56 (Transmitter) and 10.99.1.44 (Receiver). I have a L3 address on the VLAN 95 SVI on both L3 switches closest to the Transmitter (Arista) and Receiver (Cisco). I am using Sparse Mode. I also have a RP address setup on the L3 switch closest to the Transmitter and I have told the L3 switch closest to the Receiver what the RP address is. I am happy to provide more information if needed.
