Thanks for testing, raised https://github.com/armbian/build/pull/6113 to replace the binary for everyone.

Yeah, seems like hciattach binary crashes some times as reported by @Stephen Graf as well. Try replacing /usr/bin/hciattach_opi with https://github.com/orangepi-xunlong/orangepi-build/raw/next/external/packages/blobs/bt/hciattach/hciattach_opi_arm64. Make sure to keep the filename the same i.e hciattach_opi. Let me know if it works after reboot
