profiler-toolbar | Zend Framework 2 , that adds profiler

I work a lot with symfony, but this time, when i start a new project with the "symfony new my_project --full" command, i have a problem with the debug toolbar.

I only add User entity with php bin/console make:user, i add authentication with php bin/console make:auth

When i go on controller route like the login page, i can see the debug toolbar, but if i do a 404 error with the route "/qwerty", the debug toolbar isn't showing and i have a javascript error in the console who said : "Uncaught TypeError: Sfjs.loadToolbar is not a function". I have this error on every error page like 403, 500.

I try to remove and reinstall the profiler, i update composer, clear the cache, but nothing change.

I follow the instructions on this answer : My profiler toolbar isn't showing up in symfony 4.3.1 but everything seems to be ok except the 'Note' at the end of this one : only difference with answer

I try to make a new project with another PC (i thought i had a problem with my configuration), but it's the same thing.

I have a and a in my base.html.twig, the others template are extending to this one, so it's not a missing's problem.

This is all i found about this problem on my research, can you help me with this one please ?
