How did you change the password manually? Via database or BO?

Firstly, i changed the password throught phpmyadmin. then i changed the "database_password" in parameters.php. 

the store is ok . but back-office shows 500 error .

 i turn on debug mode.   here below is the screenshot. 

I forgot i installed  php8.1.    i changed back to old version of PHP7.4.     everything is ok.  

then  i closed the cache on back-office.    no problem on php8.1 

so  the problem is memcached.   how can i resoled the problem?

I sent you a PM with the way to go further.
Be nice and keep that solution to you.

the problem is PHP memcached extentions.  the version must > 3.1.5    

the prestashop require memcached >3.1.5 when php>=8.01. 

i have had a try on another server .  both php8.1  8.2  is OK.
