Fatal Error after Gutenberg

Hello,

I recently installed, or tried to, install Gutenberg plugin, but it crashed the wp-admin access. Now I can’t log in at all, but the website seems to work. I’ve accessed the FTP but the gutenberg folder is not to be found at all. I’ve also tried to revert the FTP folder into before it was introduced, but the problem still persists. I’ve tried to rename the plugins folder and the theme folder. Nothing has helped so far. What else can I do to get into the admin space again?

I get this error:

Fatal error: Uncaught Error: Call to undefined function register_block_type_from_metadata() in /var/www/gadeidraet.dk/public_html/wp-content/plugins/gutenberg/lib/blocks.php:127 Stack trace: #0 /var/www/gadeidraet.dk/public_html/wp-includes/class-wp-hook.php(287): gutenberg_reregister_core_block_types(”) #1 /var/www/gadeidraet.dk/public_html/wp-includes/class-wp-hook.php(311): WP_Hook->apply_filters(NULL, Array) #2 /var/www/gadeidraet.dk/public_html/wp-includes/plugin.php(478): WP_Hook->do_action(Array) #3 /var/www/gadeidraet.dk/public_html/wp-settings.php(540): do_action(‘init’) #4 /var/www/gadeidraet.dk/public_html/wp-config.php(88): require_once(‘/var/www/gadeid…’) #5 /var/www/gadeidraet.dk/public_html/wp-load.php(37): require_once(‘/var/www/gadeid…’) #6 /var/www/gadeidraet.dk/public_html/wp-admin/admin.php(34): require_once(‘/var/www/gadeid…’) #7 /var/www/gadeidraet.dk/public_html/wp-admin/index.php(10): require_once(‘/var/www/gadeid…’) #8 {main} thrown in /var/www/gadeidraet.dk/public_html/wp-content/plugins/gutenberg/lib/blocks.php on line 127
