Ubuntu Apache环境下ErrorDocument自定义错误页面失效问题求助（含Certbot生成的Rewrite规则）

大家好，我现在碰到个头疼的问题——Apache的自定义错误页面（ErrorDocument）死活不生效。我翻了好多论坛帖子和教程试了各种办法都没用，目前能想到的和别人情况不一样的地方，就是我的配置里有Certbot自动加上的RewriteCond规则。

之前我在旧版本Ubuntu的自签名证书站点上成功配置过，但这次在Ubuntu 22.04上就不行了。

我已经查阅了不少相关的教程、官方文档和社区问答，但都没能解决这个问题。我肯定是漏掉了什么明显的配置点，或者因为Certbot生成的Rewrite规则需要额外的处理步骤。如果有大佬遇到过类似问题或者有解决思路，欢迎帮忙指点一下，非常感谢！
