Website crashes after latest update

Hello, this morning my website crashed after updating all plugins.

WordPress-Version 6.2
Aktives Theme: Avada Child (Version 1.0.0)
Aktuelles Plugin: Easy Post Types and Fields (Version 1.1.4)
PHP-Version 8.0.28

I temporarily deactivated the plugin “Easy Post Types and Fields” via FTP to get access to the website. But I cannot activate it again, because it is causing an error message:

Warning: require(/customers/b/8/3/tanzschuleamtoensberg.de/httpd.www/wp-content/plugins/easy-post-types-fields/vendor/composer/../symfony/polyfill-mbstring/bootstrap.php): Failed to open stream: No such file or directory in /customers/b/8/3/tanzschuleamtoensberg.de/httpd.www/wp-content/plugins/easy-post-types-fields/vendor/composer/autoload_real.php on line 76 Fatal error: Uncaught Error: Failed opening required ‘/customers/b/8/3/tanzschuleamtoensberg.de/httpd.www/wp-content/plugins/easy-post-types-fields/vendor/composer/../symfony/polyfill-mbstring/bootstrap.php’ (include_path=’.:/usr/share/php’) in /customers/b/8/3/tanzschuleamtoensberg.de/httpd.www/wp-content/plugins/easy-post-types-fields/vendor/composer/autoload_real.php:76 Stack trace: #0 /customers/b/8/3/tanzschuleamtoensberg.de/httpd.www/wp-content/plugins/easy-post-types-fields/vendor/composer/autoload_real.php(59): composerRequire35294f6ac0a205fee6a08b9434ba3832(‘0e6d7bf4a5811bf…’, ‘/customers/b/8/…’) #1 /customers/b/8/3/tanzschuleamtoensberg.de/httpd.www/wp-content/plugins/easy-post-types-fields/vendor/autoload.php(7): ComposerAutoloaderInit35294f6ac0a205fee6a08b9434ba3832::getLoader() #2 /customers/b/8/3/tanzschuleamtoensberg.de/httpd.www/wp-content/plugins/easy-post-types-fields/easy-post-types-fields.php(36): require_once(‘/customers/b/8/…’) #3 /customers/b/8/3/tanzschuleamtoensberg.de/httpd.www/wp-admin/includes/plugin.php(2314): include_once(‘/customers/b/8/…’) #4 /customers/b/8/3/tanzschuleamtoensberg.de/httpd.www/wp-admin/plugins.php(192): plugin_sandbox_scrape(‘easy-post-types…’) #5 {main} thrown in /customers/b/8/3/tanzschuleamtoensberg.de/httpd.www/wp-content/plugins/easy-post-types-fields/vendor/composer/autoload_real.php on line 76

There must be a problem since your latest update to version 1.1.4.
