I can confirm this behaviour.

There is currently no new upstream version containing the fix. Applying the patch fixes the segfault but I automatically gets disconnected (error: Connection Failed: br-connection-unknown) and can't use my BT device:

asp checkout bluez
cd bluez/repos/extra-x86_64
gpg --recv-key 06CA9F5D1DCF2659
makepkg -s --nobuild
curl https://github.com/bluez/bluez/commit/8edd9ff4e4ea85c80bee00a4a46b1cae3678dea6.patch -o /tmp/bluez.patch
src/bluez-5.63
patch -p1 < /tmp/bluez.patch
cd ../..
makepkg -i --noextract
sudo systemctl restart bluetooth

What actually worked for me was downgrading to 5.61/5.62.

You can also check if you have an old package locally cached and use pacman -U /var/cache/pacman/pkg/blu???.zst
ls -l /var/cache/pacman/pkg/bluez*

cd bluez/repos/extra-x86_64
git checkout 5303f48bcc78f1167842e95fa8a4b67b7fc8aac8
makepkg -si
sudo systemctl restart bluetooth

Please try 5.63-2- it also has now debug symbols available for testing.

I can confirm that the patched v5.63-2 no longer exhibits the mentioned issue and Bluetooth now works just as it should after suspend/wake.

I've tested v5.63-2 and can also confirm that the -2 patch fixed the issue.
