Ubuntu 22.04.4 LTS热关机后蓝牙无法使用的修复求助

我用的是Ubuntu 22.04.4 LTS，之前经历了一次热关机，重启后发现蓝牙完全没法用了。出问题之前，我从Ubuntu软件商店装了Bluetooth Manager，但后来它就失效了。

听了些网上的建议后，我卸载了那个Bluetooth Manager，安装又卸载了BlueZ，之后尝试装blueman也没成功。我当时完全不懂原理就瞎折腾了一通，现在把相关操作的结果列出来：

• 运行blueman-manager时返回了截图所示的错误（截图未附上）
• 插入USB蓝牙适配器后，执行bluetooth命令得到以下输出：

  ashoke@Dell-3470:~$ bluetooth
  bluetooth = on
  

• 拔掉该适配器后，执行bluetooth命令的结果：

  ashoke@Dell-3470:~$ bluetooth
  bluetooth = none (no device)
  

• 尝试启动蓝牙服务时，运行sudo systemctl start bluetooth返回错误：

  Failed to start bluetooth.service: Unit bluetooth.service failed to load properly, please adjust/correct and reload service manager: File exists
  See system logs and 'systemctl status bluetooth.service' for details.

• 运行sudo systemctl status bluetooth.service查看状态，输出如下：

  ○ bluetooth.service - Bluetooth service
  Loaded: error (Reason: Unit bluetooth.service failed to load properly, ple>
  Active: inactive (dead)

我是Ubuntu新手，现在把系统搞乱了，能不能帮我解决这个问题？我需要一个一步步的教程来修复蓝牙故障。
