I find this same error, but on the Ubuntu Cinnamon 23.10 daily build, running all the latest packages/updates as of 9/14/23 7PM PST.
Steps to reproduce are to install the daily build, run `apt install blueman`, and attempt to run blueman.
It seems like, for me, it happens on the first bootup, and then running blueman again will get it to go, once you successfully connect a device (Bluetooth speaker in my case) it will continue running smoothly. (edit: not the case, it happened once more today simply from trying to open the app from the toolbar icon)

I've attached my blueman crash logs.
