There is many errors, but all of them are variable that have not been declared before using it, as example :
$style == 'flex' ? $flex_style = ' flex' : '';
$style == 'blog' ? $blog_style = ' blog' : '';
$blog_style = $output = '<div class="sppb-addon sppb-addon-latest-posts'.$flex_style.$blog_style.' sppb-row ' . $class . '">';
In this case $flex_style and $blog_style are not declared, you should write this instead :
$flex_style = style == 'flex' ? ' flex' : '';
$blog_style = $style == 'blog' ? ' blog' : '';
That is just an example, but if you search a little you'll find other issue like this one.
