Does anyone have any idea how should I fix this? Thank you.

Sorry, but providing an error without any context won't allow anyone to help without having to make wild guesses.

What's the document you are trying to render? What Quarto version? What system are you on? What LaTeX distribution are you using?

Please read the guidelines when you open a Q&A question: https://github.com/orgs/quarto-dev/discussions/new?category=q-a

scrartcl.cls is for Koma Script. Installing manually Koma package should help solve this. I'll let you read the related issues mentioned above too.
