Method "StopNotify" with signature "" on interface "org.bluez.GattCharacteristic1" doesn't exist

• raspberry pi 4B
• debian bookworm
• bleak 0.20.2-1 from python3-bleak package
• bluetoothctl: 5.66

Related to #1500 and #1507, see #1500 for a detailed description of my setup

Sorry for the flood of issues, but I'm not sure of these are related or not.

After some time of round-robin polling 60 BLE devices communication is no longer possible and I get the message [org.freedesktop.DBus.Error.UnknownObject] Method "StopNotify" with signature "" on interface "org.bluez.GattCharacteristic1" doesn't exist thrown

Any hints on how to debug appreciated.

Sorry for the noise - this was a side effect of my connection not properly opening due to other issues.
