Website broke after Update

It seems as if there was a Rank Math – Update.
When I tried to open my website I only got an error message.
Right after that there came an email from WordPress Support stating there was an error concerning Rank Math SEO – Plugin:

#WordPress-Version 5.3
Aktuelles Theme: Newspaper (Version 10.1)
Aktuelles Plugin: Rank Math SEO (Version 1.0.35.1)
PHP-Version 7.2.24###
