gantry 5 CB menu throws Exception

Hi, 
Using latest Joomla 4, Gantry 5 and CB versions. Any attempt to select/activate any CB menu item throws the following exception messages:

```
Error: During inheritance of Countable: Uncaught Whoops\Exception\ErrorException: Return type of Twig\Node\Node::count() should either be compatible with Counta ▶

you can try it here: tst.beetonrcflyers.org

any help to get this resolved would be appreciated.  I posted a similar question on gantry’s forum, but I suspect this is a CB issue

We're not the developers of Gantry 5 or your template. Please contact the developer of your template.

Why would you suspect CB? The error nor the stack trace has no mention of CB. The error points directly at them using an old version of Twig, which isn't compatible with your version of PHP (guessing 8.1 in this case). It appears to already be reported to them on Github.

Many thanks for the prompt response. At least it gives me a clue where to push next.

BTW the reason I suspected CB was because it is the only Joomla component I have that misbehaves, but I’m happy to be shown that my suspicions were wrong.

Misbehaves in what way? If you're experiencing a bug in CB itself please be sure to report it. We certainly try to make CB as stable as possible.

sorry for the confusion - misbehave => as in throwing the exception.  As you suggested it appears to be a stale twig version, but I was trying to say that CB was the only Joomla component that throws that exception.
