Phpmyadmin issue when php update

[Wolf_TMB]

Hello, I am trying to install php 8 on a server, everything works fine except phpmyadmin (error 500).
In doing so, installed php version 7.4
a2dismod php7.2
a2enmod php7.4
systemctl restart apache2
The version changes, phpmyadmin is working. When changing to php8.0, it stops working. There are no errors in the Apache logs.
What could be the problem?
