Front matter block causing error on Windows

[akarel-mb]

On a Windows machine (Windows 11), if I include the yaml matter block and run presenterm [path] I get the following error:

invalid presentation metadata: deserializing from YAML containing more than one document is not supported

If I remove the block, the presentation renders as expected.

The following works...

Header
---

This is a test.

<!-- end_slide -->

But this does not...

---
title: Test
author: Test
---

Header
---

This is a test.

<!-- end_slide -->

Forgot to add, I'm using presenterm version 0.4.1
