开机卡在启动阶段，提示Failed to start nmbd.service的问题求助

大家好，我的PC开机时卡在启动环节了，屏幕一直显示Failed to start nmbd.service的错误提示，没法正常进入系统。我试着查了一些相关状态信息，整理如下：

执行systemctl status nmbd.service的输出： #

Loaded: loaded(/lib/systemd/system/nmbd.service; disabled; preset: enabled)
Active: inactive (dead)

执行sudo journalctl -xeu nmbd.service的输出： #

The unit nmbd.service has entered the 'failed' state with result 'timeout'
A Start job for unit nmbd.service has finished with failure
The job identifier is 1366 and the job result is failed

执行testparm -s | grep interfaces的输出（顺便发现了两个目录不存在的警告）： #

Load smb config files from /etc/samba/SMB.CONFIG
Loaded services file OK.
Weak crypto is allowed by GnuTLS (e.g. NTLM as a compatibility fallback)
Warning: lock directory /run/samba does not exist
Warning: pid directory /run/samba does not exist

Server role: Role_STANDALONE

另外附上两张相关截图：

• 开机时的错误提示截图：
  
• journalctl命令的完整输出截图：
  

有没有大佬能帮忙看看这个问题怎么解决呀？
