I also faced this issue after updating my node version to 19.x. But then I updated my node version to latest stable version and this issue was resolved. Try updating your node using following steps on this link:

CodePudding user response：

The version of angular should be compatible to certain node version. The LTS node version support to some extent for angular version. For eg. currently angular version 15 is compatible with node version ^14.20.0 || ^16.13.0 || ^18.10.0 (all with LTS).

For the Reference check out already asked Question regarding compatibility of angular and node version
