Ubuntu 22.04 LTS 以太网无法正常工作的求助

各位技术大佬，我最近碰到个头疼的网络问题，实在搞不定了，求帮忙！

之前在Fedora系统上，我的以太网就没法正常工作——网卡能被系统检测到，但就是连不上网。不过WiFi和USB共享网络都没问题，而且在双系统的Windows里，以太网完全能正常使用。

后来我干脆把Fedora彻底重装成了Ubuntu 22.04 LTS，结果问题居然还存在！就连用Ubuntu Live USB启动的时候，以太网也还是没法用。我甚至手动配置了IPv4参数，还是没效果，这个问题已经拖好几天了，实在没辙了，求各位支支招！

下面是我通过journalctl -u NetworkManager命令导出的网络日志关键片段：
