Prestashop 9.0 install errors

[Rhettyx]

I installed prestashop 9.0 in wsl2+ubuntu in my win10 computer. The platform configuration is: PHP 8.3.6、Apache 2.4.58、MariaDB 15.0. The installation process is smooth. I can open the frontend, but when I click the back office. It got 500 error. 

Please check this video: https://www.loom.com/share/8bf2c2386019427caf79bac8d9330867?sid=4ee56a61-feca-4cf2-90f9-c189be3539d8

Then I checked the appach error log, and found below errors:

I checked the errors in Grok AI. It provided several solutions: repair PHP session permission, repaire PHP fatal error (signature incompatibility), and other minor errors.

I followed just repair PHP session permission solution, and now I can log into back office, but when I checked the apache error, the errors persist.

3 commands to repair PHP session permission:

sudo chown www-data:www-data /var/lib/php/sessions
sudo chmod 770 /var/lib/php/sessions
sudo rm -rf /var/lib/php/sessions/sess_*

Please help me solve the other errors.
