It's a know issue (https://github.com/php-fig/container/issues/30) but psr\container version 1.1.1 on PHP7.4 should fix the problem. — Dimitri Mostrey, Apr 22 '21 at 12:37
Remove your composer cache `composer clearcache` , delete your `vendor` folder and then run `composer install` — Hedayatullah Sarwary, Apr 22 '21 at 12:40

Remove your composer cache by the command below:

composer clearcache

Then remove the vendor folder and run composer install. I hope this solution help you.

the Problem was after upgrading PHP I had to update the nginx vhost at sudo nano /etc/nginx/sites-available/nginx_vhost by changing the old PHP7.1-fpm.sock to PHP7.4-fpm.sock From

    location ~ \.php$ {
 
        fastcgi_pass unix:/var/run/php/php7.1-fpm.sock;
   
    }

To

    location ~ \.php$ {
 
        fastcgi_pass unix:/var/run/php/php7.4-fpm.sock;
   
    }
