Angular 12生产构建后IE 11报TypeError: Object不支持此操作如何解决？

我已知IE11的支持已被官方废弃，但客户及合同要求必须兼容该浏览器。目前项目本地运行时可在IE11中正常打开，但执行生产构建后部署出现报错：仅页头、页脚正常渲染，其余页面内容完全空白。经大量搜索该报错及Angular 12兼容IE11的相关解决方案，仍无法解决，特此求助。
我无法降级到Angular 11或更低版本，因为项目使用的身份验证包angular-auth-oidc-client要求依赖Angular 12版本。

报错截图：
报错信息：Uncaught (in Promise): TypeError: "Object doesn't support this action at value

已尝试直接引入完整的core-js库，仍出现相同报错。
