The Keynote not compatibel with Wordpress 5.5?

Hello, if i upgrade my website to Wordpress 5.5, then some components from the theme doesn’t work.
The text in the Master Slider isn’t visible on the website.
The option caroussel by item options doesn’t work.

Maybe I’m doing something wrong, but i hope someone can help me with this.

Thank you
