Why am I getting 'cannot redefine property' error when updating application to angular 14

I recently did an update to angular v14 and since then I got this error when I try to run my application:

Uncaught TypeError: Cannot redefine property: addHours
at Function.defineProperty ()
at 64434 (date.extensions.ts:7:8)
at webpack_require (bootstrap:19:1)
at 37562 (services.module.ts:17:41)
at webpack_require (bootstrap:19:1)
at 53907 (main.ts:13:37)

I tried to find what package makes this fail but I haven't found it yet.

My code:

declare interface Date {
  addHours(hours: number): Date;
  addMinutes(minutes: number): Date;
}

Object.defineProperty(Date.prototype, 'addHours', {
  configurable: true,
  enumerable: false,
  value: function(hours: number) {
    const date = new Date(this.valueOf());
    date.setHours(date.getHours() + hours);
    return date;
  }
});

Object.defineProperty(Date.prototype, 'addMinutes', {
  configurable: true,
  enumerable: false,
  value: function(minutes: number) {
    const date = new Date(this.valueOf());
    date.setMinutes(date.getMinutes() + minutes);
    return date;
  }
});
