Can you share the YAML header you use to get this error ? I am suprised that create_output_format() is called for a Quarto document ?
Running the default template for Quarto document in the IDE works for me
---
title: "Untitled"
format: docx
editor: visual

## Quarto
Quarto enables you to weave together content and executable code into a finished document. To learn more about Quarto see <https://quarto.org>.
## Running Code
When you click the **Render** button a document will be generated that includes both content and the output of embedded code. You can embed code like this:
```{r}
1 + 1
```
You can add options to executable code like this
```{r}
#| echo: false
2 * 2
```
The `echo: false` option disables the printing of code (only output is displayed).
