Bluetooth headphones disconnect immediately

I have Sony WH1000XM3 headphones which used to run fine on Ubuntu 20.04. I ran a few updates earlier this week and this seems to have messed up with my bluetooth settings. Headphones work fine with my cellphone.

Here are the messages from journalctl corresponding to the event when the headphones connect and then immediately disconnect:

And here are the infos from systemctl status bluetooth

So far I have tried reinstalling bluez, but without any success. I have no idea what the problem may be.

also lsb_release output

No LSB modules are available.

Same problem here with Kububuntu 21.10. Sometimes I've gotten the connection to hold, but I still can't switch the output over to it. Bluetooth doesn't show up as an output device in pavucontrol (volume control), which is where I would normally switch the audio from the computer's speakers to my headphones.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
