Please describe your issue in as much detail as possible:

Attempting to connect repeatedly to multiple Bluetooth devices can cause the Bluetooth service (bluetoothd) to break or Steam to soft-reset. From the two devices I've tested on, the behaviours were different, but repeatable on each. On a LCD, Steam soft reset as a result of multiple Bluetooth connection attempts. On an OLED, Steam remains responsive, but Bluetooth no longer functions (systemctl shows the service failed or if it was still running any actions would return org.bluez.Error.Busy).

Steps for reproducing this issue:

1. Navigate to Steam > Settings > Bluetooth.
2. Toggle Show all devices to on.
3. Navigate to an entry under Available to Pair.
4. Press A on the selected device and continue pressing A.
5. You can also spam all available devices which can speed up the repro

Reproduction Rate: 5/5, but can take from just a few to many, many connection / cancel attempts.

Affected Platforms

• LCD / Jupiter: Yes
• OLED / Galileo: Yes
• Desktop Deck-like session (gamescope -e -- steam -gamepadui -steamdeck): N/A
• Desktop: N/A

Note: Bluetooth devices are not managed by Steam in Desktop Mode or on Desktop.

Actual result

• Steam crashes and / or bluetoothd service stops responding.

Expected result

• Steam does not crash and bluetoothd remains responsive.

Notes

• I was unable to reproduce this issue in Desktop Mode via KDE's "Add Bluetooth Device".
• I was unable to reproduce this issue via terminal using bluetoothctl or bluetuith.
