 https://webolute.com/blog/programming/this-may-be-due-to-a-blocked-port-missing-dependencies/

and for My sql, use below steps

Open the XAMPP Control Panel and click Config next to MySQL, then select my.ini.

Find the lines port=3306 (usually in two places) and change them to port=3307.

next step

If going to localhost:8000 get error than change the config.inc.php, enter the password in string $cfg['Servers'][$i]['password'] = 'root';

and change

$cfg['Servers'][$i]['controluser'] = 'pma'; to  $cfg['Servers'][$i]['controluser'] = 'root';

$cfg['Servers'][$i]['controlpass'] = '';$cfg['Servers'][$i]['controluser'] = 'root';

=========================================

C:/xampp/php/php.ini

C:/xampp/apache/conf/httpd.conf

C:/xampp/mysql/bin/my.ini

C:/xampp/phpMyAdmin/config.inc.php

These above 4 files are changed.

C:/xampp/phpMyAdmin/config.inc.php

/* Authentication type and info */

$cfg['Servers'][$i]['auth_type'] = 'config';

$cfg['Servers'][$i]['user'] = 'root';

$cfg['Servers'][$i]['password'] = 'root';

$cfg['Servers'][$i]['extension'] = 'mysqli';

$cfg['Servers'][$i]['AllowNoPassword'] = true;

$cfg['Lang'] = '';

/* Bind to the localhost ipv4 address and tcp */

$cfg['Servers'][$i]['host'] = '127.0.0.1:3306';

$cfg['Servers'][$i]['connect_type'] = 'tcp';

/* User for advanced features */

$cfg['Servers'][$i]['controluser'] = 'root';

$cfg['Servers'][$i]['controlpass'] = 'root';

and for xampp server- default password is blank

$cfg['Servers'][$i]['auth_type'] = 'config';

$cfg['Servers'][$i]['user'] = 'root';

$cfg['Servers'][$i]['password'] = '';

$cfg['Servers'][$i]['extension'] = 'mysqli';

$cfg['Servers'][$i]['AllowNoPassword'] = true;

$cfg['Lang'] = '';

/* Bind to the localhost ipv4 address and tcp */

$cfg['Servers'][$i]['host'] = '127.0.0.1:3307';

$cfg['Servers'][$i]['connect_type'] = 'tcp';

/* User for advanced features */

$cfg['Servers'][$i]['controluser'] = 'root';

$cfg['Servers'][$i]['controlpass'] = '';

C:/xampp/mysql/bin/my.ini - How to change the port of Mysql in xampp

port=3306

socket="C:/xampp/mysql/mysql.sock"

# Here follows entries for some specific programs 

# The MySQL server

default-character-set=utf8mb4

C:/xampp/apache/conf/httpd.conf(How to change port of Appache server in xampp) 

For changing https port

Listen 80 -- change here

ServerName localhost:80

C:/xampp/php/php.ini

if getting error "plugin does not exist. Valid plugin IDs for Drupal\Core\ImageToolkit\ImageToolkitManager are: gd in Drupal\Core\Plugin\DefaultPluginManager-"

1) Press Ctrl + F and search for ;extension=gd.

2) Remove the semicolon (;) at the beginning of the line so it looks like this: extension=gd.

3) restart xaamp server

and

Add or uncomment the following line in your php.ini file: zend_extension=opcache.

Verify Settings: Ensure opcache.enable=1 is set in your php.ini.

c:\xampp\apache\conf\extra\httpd-ssl.conf

SSL port 4443

c:\xampp\apache\conf\extra\httpd-xampp.conf

if appache is not running than change this file.

c:\xampp\mysql\bin\my.ini

port=3307

C:\xampp\htdocs\PRGIWebsitedrupal\sites\default\settings.php

$config['system.image']['toolkit'] = 'gd';

Note:- In settings.php file port can be 3306 of Mysql workbench client and In My.ini port can be different(3307) because appache server my sql is different and mysql workbench is different.
