执行CIS加固配置账户锁定后无法登录系统求助

各位大佬紧急求助！我最近按照CIS 5.4.2的要求配置系统账户锁定（用faillock），结果配置完重启系统后，不管是root账户还是其他普通账户，哪怕输入正确密码也完全登不上了，现在系统直接卡在这里，急得不行！

这是我修改后的/etc/pam.d/common-auth文件内容（后面的省略内容就不贴了）：

# /etc/pam.d/common-auth - authentication settings common to all services
#
# This file is included from other service-specific PAM config files,
# and should contain a list of the authentication modules that define
# the central authentication scheme for use on the system
# (e.g., /etc/shadow, LDAP, Kerberos, etc.).  The default is to use the
# traditional Unix authentication mechanisms.
#
# As of pam 1.0.1-6, this file is managed by pam-auth-update by default.
# To take advantage of this, it is recommended that you configure any
# local modules either before or after the default block, and use
# pam-auth-update to manage selection of other modules.  See
# pam-auth-update(8) for details.

# here are the per-package modules (the "Primary" block)
auth    [success=1 default=ignore]      pam_unix.so
#...（剩余配置内容省略）

我怀疑是PAM的规则配置出了问题，但翻来覆去检查也没找到具体错误点，有没有大佬能给我指个排查方向，或者直接告诉我怎么修复这个问题，让我能重新登录系统？
