Twig templates are not loading
To disable cache for development(tiwg + Drupal cache) :

first copy and rename the sites/example.settings.local.php to be sites/default/settings.local.php

then open settings.php file in sites/default and uncomment these lines:

# if (file_exists(__DIR__ . '/settings.local.php')) {
#   include __DIR__ . '/settings.local.php';
# }


Now open settings.local.php and change the below lines to "TRUE".

$config['system.performance']['css']['preprocess'] = FALSE;
$config['system.performance']['js']['preprocess'] = FALSE;


and uncomment all these to Disable the render cache and Disable Dynamic Page Cache

# $settings['cache']['bins']['render'] = 'cache.backend.null';
# $settings['cache']['bins']['dynamic_page_cache'] = 'cache.backend.null';


for twig cache open "development.services.yml" and update the below parameters.

  twig.config:
    debug : true
    auto_reload: true
    cache: false
