Ubuntu 22.04 bluetooth not finding devices (specifically a bluetooth speaker)

I have a Soundcore Select 2 and my Ubuntu 22.04 isn’t able to pair with it. The hardware is a HP Prodesk 600 G4DM.

If on startup, on the black screen before the Ubuntu logo shows up, I see some error message briefly about hc10 unable to start, failure to start, or something like that, then when I go to Settings > Bluetooth > Enable the "Devices" will have a little spinning circle that will spin forever with no devices showing even though I have put the Soundcore Select 2 into pairing mode and physically placed it right next to the computer.

If there is no error message during start up, I can see the Soundcore Select 2 appear under "Devices" with the words "Not set up". I tried clicking on the Soundcore Select 2 option hoping to set up but clicking it just makes it disappear from the list briefly before reappearing again.

An image of what the bluetooth settings looks like - it shows the bluetooth speaker but clicking it makes it disappear, the Devices wheel spins, then the speaker reappears still saying "Not set up"

Initially, I thought it was the audio/sound card that is not working but when I tried alsamixer, it is able to display the sound card as "HDA Intel PCH" and the sound chip as "Conexant CX20632", which I think is correct.

I've tried other sources of audio like plugging headphones into TRS jacks and audio output works fine.

@David Yeah, looks like restarting helped it find the listing but it doesn't connect/isn't able to set up.

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.
