Fatal exception of type "Error" when using PortableInfobox on MediaWiki version 1.41.0

[Vistulis]

Hello there, I'm not sure if this is just me being terrible at MediaWiki but I've encountered a problem with infoboxes.
I'm running:

MediaWiki | 1.41.0
PHP | 8.2.16 (apache2handler)
ICU | 64.2
MariaDB | 10.4.17-MariaDB 1.41.0

The problem occured after I created an infobox using Special:InfoboxBuilder. I used the default infobox it gives you and it still occurs.
This is the code it generated:

<infobox>
	<title source="title">
		<default>{{PAGENAME}}</default>
	</title>
	<image source="image"/>
	<data source="data1">
		<label>Label</label>
	</data>
	<data source="data2">
		<label>Label</label>
	</data>
</infobox>

On the page of this infobox, this can be seen:

[Zd@NDtviGM7mnxza@dD18gAAAAM] 2024-02-28 19:44:15: Fatal exception of type "Error"

If I enable exceptionDetails then it shows this long error:

[Zd@NOhcxlNYDHLEc009VwwAAACw] /index.php/Template:TestInfobox Error: Value of type bool is not callable

The theme I'm using is Cosmos, not sure if that would affect anything.
And the extensions I've installed are VisualEditor 0.1.2 and PortableInfobox 0.6

I hope I haven't missed anything really obvious, thank you in advance for anything.
