I have added a page builder field to my admin form but it seems I can't apply any templates (the dialog doesn't show up and neither do any errors) and configure any elements (same behaviour). I can save templates no problem.
The code for the form element:
<field name="short_content" formElement="wysiwyg" sortOrder="10">
<argument name="data" xsi:type="array">
<item name="config" xsi:type="array">
<item name="source" xsi:type="string">Category</item>
</item>
</argument>
<settings>
<additionalClasses>
<class name="admin__field-wide">true</class>
</additionalClasses>
<label translate="true">Short Content</label>
<dataScope>short_content</dataScope>
</settings>
<formElements>
<wysiwyg>
<settings>
<wysiwyg>true</wysiwyg>
</settings>
</wysiwyg>
</formElements>
</field>
