WordPress automatically removes line break

When writting a description for a Woocoomerce Product and inserting a line break with br or p Tag, WordPress automatically removes it. This is really annoying because on some points, i want to have a little line break.

I often found the solution to install TinyMCE. After that now WordPress doesnt removes the p Tag anymore but inserts a nbsp inside of it and so the line break is way to big.

So i want a line break like a p Tag, because npsb produces way too much space between two sentence.

I also tried following solutions:

1. add some attributes to the p Tag like p data-x /p

2. Wrap the p Tag with comments like

!-- wp:html -- p class=beer/p !-- /wp:html --

3. Added some hooks in the functions.php like

add_shortcode(br, br_tag); function br_tag(){ return(br/); }

or

remove_filter('the_content', 'wpautop'); remove_filter('the_excerpt', 'wpautop');

and

remove_filter( 'the_content', 'wpautop' ); remove_filter( 'the_excerpt', 'wpautop' ); function wpse_wpautop_nobr( $content ) { return wpautop( $content, false ); } add_filter( 'the_content', 'wpse_wpautop_nobr' ); add_filter( 'the_excerpt', 'wpse_wpautop_nobr' );

4. I tried following solution but it doesnt work Wordpress automatically adding nbsp;?

The best solution i found was to NOT using the visual AND the text editor, but for me thats such a temporary one.

Specs:

WordPress 5.6

Advanced Editor Tools (previously TinyMCE Advanced): 5.6

WooCommerce: 4.6.1 (but in my opinion, its not a WooCommerce problem)

Does anyone know a better solution or a reference for that problem?
