[Solved] Bluetooth crashing on headset connect

I'm trying to connect a pair of TWS earbuds to a fresh install of Archlinux, and currently facing a strange issue. Whenever I try to connect to the device, for a split second the status changes to "Connected" and I get the beep indicator on the earbuds, but then it disconnects and bluetooth segfaults:

output on dmesg:

    [   91.181051] input: Soundcore Space A40 (AVRCP) as /devices/virtual/input/input20
    [   91.299701] bluetoothd[357]: segfault at 20 ip 0000558489199fa5 sp 00007fff99f0dbc0 error 4 in bluetoothd[55848917e000+d4000] likely on CPU 5 (core 1, socket 0)

status of the bluetooth daemon:

    Jul 01 18:51:17 my-laptop bluetoothd[2331]: Endpoint registered: sender=:1.54 path=/MediaEndpoint/A2DPSink/sbc_xq_552

    Jul 01 19:13:39 my-laptop systemd[1]: bluetooth.service: Failed with result 'core-dump'.

when using bluetoothctl to connect to the device:

I've found a similar issue reported on this forum regarding the bluez package (https://bbs.archlinux.org/viewtopic.php?id=260780)
Is downgrading my only solution here, what else can I test?

Re: [Solved] Bluetooth crashing on headset connect

That did it!

Lucky of me to just test this with a buggy bluez version right after a fresh install
