SUMMARY
I have a pair of Bose QC35 II bluetooth headphones paired to my computer, which is running Plasma 6.2.1 on Arch Linux (EndeavourOS).

On Linux 6.11.3 and prior, the headphones would connect automatically when turned on, but after upgrading to 6.11.4 they don't. To work around this, I need to open bluetooth settings and manually click Connect on the headphones. I need to do this each time the headphones are disconnected, which includes turning them off or rebooting.

I haven't changed any other packages: downgrading only Linux from 6.11.4 to 6.11.3 resolves the issue.

STEPS TO REPRODUCE
1. Be on Linux 6.11.4
2. Turn on paired bluetooth headphones

OBSERVED RESULT
The paired bluetooth headphones do not automatically connect to the computer when turned on.

EXPECTED RESULT
The paired bluetooth headphones automatically connect to the computer when turned on.

SOFTWARE/OS VERSIONS

ADDITIONAL INFORMATION
I'm using the Wayland session.
