edit: update acf plugin fixed it.

If you can’t update here is a code to fix it:

function acf_filter_rest_api_preload_paths( $preload_paths ) {
    global $post;
    $rest_path    = rest_get_route_for_post( $post );
    $remove_paths = array(
        add_query_arg( 'context', 'edit', $rest_path ),
        sprintf( '%s/autosaves?context=edit', $rest_path ),
    );

    return array_filter(
        $preload_paths,
        function( $url ) use ( $remove_paths ) {
            return ! in_array( $url, $remove_paths, true );
        }
    );
}
add_filter( 'block_editor_rest_api_preload_paths', 'acf_filter_rest_api_preload_paths', 10, 1 );
