Symfony version(s) affected: 4.3.0

Description
The web profiler tollbar is throwing an error "An error occurred while loading the web debug toolbar." on every page, when getting http://127.0.0.1:8000/_wdt/xxxxxx.

How to reproduce
I'm not sure what triggered this, but I suspect upgrading to 4.3. I use vue..js and an API.
The bundle "symfony/profiler-pack": "*" is probably up to date since I ran the dependencies update with composer.

Additional context
Google doesn't know this error!
Here's a part of the stack trace shown on http://127.0.0.1:8000/_wdt/xxxxxx :

(1/3) RuntimeErrorImpossible to access an attribute ("nb_errors") on a string variable ("O:39:"Symfony\Component\VarDumper\Cloner\Data":6:{s:45:"Symfony\Component\VarDumper\Cloner\Datadata";a:2:{i:0;a:1:{i:0;a:1:{i:1;i:1;}}i:1;a:3:{s:5:"forms";a:0:{}s:13:"forms_by_hash";a:0:{}s:9:"nb_errors";i:0;}}s:49:"Symfony\Component\VarDumper\Cloner\Dataposition";i:0;s:44:"Symfony\Component\VarDumper\Cloner\Datakey";i:0;s:49:"Symfony\Component\VarDumper\Cloner\DatamaxDepth";i:20;s:57:"Symfony\Component\VarDumper\Cloner\DatamaxItemsPerDepth";i:-1;s:54:"Symfony\Component\VarDumper\Cloner\DatauseRefHandles";i:-1;}").

Thanks, it was indeed the same problem.
I solved it by changing the version of symfony/console, which used to be set to 4.2.* :

"symfony/console": "4.3.*"
 "symfony/form": "4.3.*"

        "symfony/profiler-pack": "^1.0"
    }
}

composer show :
[...]

EDIT : Nevermind, My composer.json was out of date
I've updated every package to ^4.3

I think it started working fine after I installed
"symfony/twig-bridge": "^4.3", "symfony/twig-bundle": "^4.3",
