Bug on SharePoint 2019: cannot modify, create and no toolbar on modern page

Question

Hello !

I'm just starting a fresh install of SharePoint 2019 Standard (on premise) on a Windows Server 2022 Standard.

I have created a collection site called "Communication Site" as you can see below :

And this is the error message when I visite this new site :

I have no toolbar, even if I am admin.

I cannot create or edit anything.

If I click on "Modify", I get this error message : "Could not modify this page. We're sorry, we encountered an unexpected error. Please try again, if the problem persists please contact your Administrator”

However, If a create a new Collection Site with a "classic experience" like "Team Site" like below, I don't have problem anymore

Any idea of what's happen ?

I found the cause.
My SP server hostname is : intranet.mydomain.local
My web app name is : intranet
For SSL Certificate reason, I have to access my site by the URL https://intranet.mydomain.local/sites/portal
I solve my issue by recreating my web app with the name and URL "intranet.mydomain.local" instead of just "intranet".
