Angular 15宣称支持TypeScript 4.9.3却出现版本兼容报错求助

我正尝试将项目升级至TypeScript 4.9.3，根据Angular官方文档，最新的Angular 15版本应当支持该TypeScript版本。但无论进行何种操作，始终出现如下报错：

Error: Failed to initialize Angular compilation - The Angular Compiler requires TypeScript >=4.8.2 and <4.9.0 but 4.9.3 was found instead.

我无法理解为何Angular编译器要求TypeScript版本需小于4.9.0？附上我的package.json配置文件，恳请各位帮忙排查问题：
