H Salvatore,
it seems to be an Debian configuration problem which still exist in kernel 6.5.
I checked the current Ubuntu Live version with success. Everything works as expected.
Maybe the Bluetooth configuration is buggy. A second problem I have is choppy sound with all of my bluetooth headphones (MM500 from Sennheiser - an old one) and Sony WH-1000XN3 (a newer one)

Here are the results: beginning right after clicking "add device" until the device manager says "not able to pair" Just Debian 6.1.37-1 works. #1 SMP PREEMPT_DYNAMIC Debian 6.3.11-1 (2023-07-01)6.4.4-1 was uploaded to unstable in meanwhile, you might be able to check against the newer version as well?
