CI4 latest verion, installation, Error 500!

I do not know what I am doing wrong but for 2 days I have been trying to install Ci4.  It is very stange as I have a perfectly running CI4 4.1.9 and replicated everything for a new domain but is just dies with 500 error:

Apache2 on unbuntu config

Code:

<IfModule mod_ssl.c>
<VirtualHost *:443>
    ServerAdmin [email protected]
    ServerName  www.example.com
    ServerAlias www.example.com
    DocumentRoot /var/www/example.com/public_html/public
    ErrorLog ${APACHE_LOG_DIR}/example.com.error.log
    CustomLog ${APACHE_LOG_DIR}/example.com.access.log combined
    SSLCertificateFile /etc/letsencrypt/live/example.com/fullchain.pem
    SSLCertificateKeyFile /etc/letsencrypt/live/example.com/privkey.pem
    Include /etc/letsencrypt/options-ssl-apache.conf
</VirtualHost>
</IfModule>

I moved env to .env and changed

Code:

CI_ENVIRONMENT = development
app.baseURL = 'https://www.example.com'

My .htaccess file is in /public and as follows;

Code:

#AuthType Basic                                                                                                                               
#AuthName "My Protected Area"

    # can be sent to index.php, and everything works as normal.

Here are my trouble shooting steps:
- yes, restarted apache2
- If I put in a phpinfo.php and go to www.example.com/phpinfo.php it works
- tried the htaccess from the github reposiory.  The only diff is my htpasswd header which I have of course disabled.
- checked the user of apache and chwon'ed it to sudo chown -R www-data:www-data /var/www/ just in case
- /writable is writable

Any pointer super appreciated.  I originally used CI a lot but move to wordpress.  Wordpress is quite robust but it is very slow because of that.  Back to Ci4 as it is blazingly faster.  I love the new SHEILD and SETTINGS which I can't wait to try out.

Regards

To fix this, i was able to see in the apache log files that it was complaining about the version of composer I had. I did composer self-update and reinstalled. It works.
