The profile appears to be in use by another Chromium (2210) on another computer (先前的主机名). 程序名 has locked the profile so that it doesn’t get corrupted. If you are sure no other processes are using this profile, you can unlock the profile and relaunch 程序名 然后 点击 ublock正常使用 但是一关机重启 就全部恢复成原来的样子和配置 根本不能保存
