Would adding this else statement to the file be sufficient? This should solve any solve any issues with fieldsets not being rendered.

		Component-Builder/admin/src/View/Compiler/HtmlView.php
		Lines 174 to 177 in 2fab51f611
	
					public function getDynamicForm(): ?Form

					{		

						if(ArrayHelper::check($this->Components))

						{

else {
// start the form
			$form = new Form('Builder');

			$form->load('<form
				addruleprefix="VDM\Component\Componentbuilder\Administrator\Rule"
				addfieldprefix="VDM\Component\Componentbuilder\Administrator\Field">
					<config><inlinehelp button="show"/></config>
					<fieldset name="builder"></fieldset>
					<fieldset name="advanced"></fieldset></form>');

			// No components found
			$attributes = [
				'type' => 'note',
				'name' => 'nocomponentnote',
				'label' => 'COM_COMPONENTBUILDER_NO_COMPONENT_NOTE_LABEL',
				'description' => 'COM_COMPONENTBUILDER_NO_COMPONENT_NOTE_DESCRIPTION'
				];

			// add to form
			$xml = FormHelper::xml($attributes, $options);
			if ($xml instanceof \SimpleXMLElement)
			{
				$form->setField($xml, null, true, 'builder');
			}

We added a no component template 👍 I have never used JCB empty... so I never bothered.

We are rushing out a next stable release, for V5 and V6 to address some urgent bugs and security fixes, so we will add this to it 😉 (for fun)
