It seems the system can't find the default adapter. I've run the following commands. Hopefully, they will provide all the info required. If not, please ask, I'll post additional information.

sudo blueman-manager
blueman-manager 10.12.58 ERROR    Manager:137 on_dbus_name_appeared: Default adapter not found, trying first available.
blueman-manager 10.12.58 ERROR    Manager:141 on_dbus_name_appeared: No adapter(s) found, exiting

sudo bluetoothctl

[bluetooth]# show

Your title appears to have a wrong version number based with the tag you have used. You may want to correct this.

Processor is not relevant is it a laptop using a built-in BT device? What is the BT adapter?

This device isn't supported by Ubuntu kernels. You can try a mainline kernel. https://forums.linuxmint.com/viewtopic.php?p=2219172&sid=95448aedc7738b9974a154a5765be4e1#p2219172

This Bluetooth adapter is not supported by Ubuntu kernels yet.

You can install a mainline kernel to get it working.

You can use https://kernel.ubuntu.com/~kernel-ppa/mainline/ or another way. Kernel 6.0 should work.

Worked with mainline kernel v6.0 (Did not work for v5.19).

Don't give up- Persevere.
I physically broke my little USB-Bluetooth adapter last week on my old Lenovo Thinkpad.
The old dongle is now a dangle. I managed to pry it out of the laptop's USB-port, and then ordered the least-expensive bluetooth adapter I could find on Amazon: The TP-Link UB400. $9.
I never thought of checking to see if it runs on Linux, until I plugged it in and the standard Bluetooth would not find any devices. After reading all kinds of defeatist online comments- "TP-Link Bluetooth devices WILL NOT run on Ubuntu 22.04!", I eventually found an answer I liked.
So I installed Blueman-manager 2.2.4 - (sudo apt install blueman) and THIS found my DOSS-Soundbox speaker, albeit as "headphones".
I have yet to dual boot the laptop into Win-10 and try the UB400 there. Gee.. I sure hope it's supported in Windows! ;-)

How does this answer the question?

I sit in a Tesla and translated this thread with Ai:

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.
