Pattern(/^[^+%{}~?^:#!|=*;,\[\]<>"'`\¿\-]*$/) not accepting chars x,f,b on prod build while working on dev build for Validators

I have Angular project with the following pattern with a file app.component.ts which is like as follows and I'm using angular validator version "@angular/forms": "^14.2.0" :

import { FormBuilder, FormGroup, Validators } from '@angular/forms';

 [
          Validators.required,
          Validators.pattern(/^[^+%{}~?^:#!|=*;,\[\]<>"'`\¿\-]*$/),
          Validators.maxLength(64)
        ]

And my html file as app.component.html :

<form [formGroup]="myForm">
  <label for="name">Name:</label>
  <input type="text" id="name" formControlName="name" />

  <div *ngIf="myForm.get('name')?.hasError('required')">
    Name is required.
  </div>

  <div *ngIf="myForm.get('name')?.hasError('pattern')">
    Invalid characters in the name.
  </div>

  <div *ngIf="myForm.get('name')?.hasError('maxlength')">
    Name should not exceed 64 characters.
  </div>
</form>

Kindly let me know why this pattern is not accepting x,f,b on production build while same is working on dev build for validator framework
