Bluetooth drops every time CarPlay is connected

I never had a problem until one month ago. Anytime I try to connect CarPlay. My Bluetooth is dropped as a result. I cannot make any phone calls and I have no audio. My wired connection no longer allows for phone calls or audio. I have an Apple 15 Pro Max. My software is up to date. Now I have no volume with my navigation or music or phone calls volume . I have reset my network settings , tried repairing and forget the device as well as everything else. Nothing works. I am beyond frustrated.
