Hi! From the logs this seems to just be a connection issue. Have you tried the troubleshooting tips in the Home Assistant documentation on Bluetooth?
A few other questions/suggestions:

• Are you sure you do not have another device like your phone that is still paired with it? (they could be fighting to connect)
• Is your mug close to the Raspberry Pi? If not, do you have fewer issues closer?
• I see the Home Assistant documentation says there are reliability issues with the Pi 3 and 4, not sure if that applies to the 5 as well.
• Do you have anything that may cause interference?
• Do you have another dongle or ESP32 you could try to see if that works better?
• Have you tried removing the device and adding it again (remove device and remove via bluetoothctl)
• Are you running Home Assistant OS directly on the PI or are you doing some kind of device passthrough that could be causing problems?

Hey I also thought maybe plain old signal strength but I know nothing. I am using HA OS direct (on nvme if it matters) and I tried the pi is in the center of my small house so it's no more than 20ft at any moment but I realize interference can easily defeat 20ft. not paired with my phone or any other device. I did remove and re-add a few times as well as hot pair it same works for a few minutes then gone. even if the mug hasn't moved, on or off the charger.

I am building a full pc now for HA as I want best all local voice performance so in a few days Ill be using a z790 mobo with external bt antenna so things will likely be way different
