Installation error with ddev and TYPO3 12.4.25

[Hobokens]

After the installation ddev composer req porthd/timer I get the error message:

<br />
<b>Fatal error</b>:  Declaration of Porthd\Timer\Command\UpdateTimerCommand::execute(Symfony\Component\Console\Input\InputInterface $input, Symfony\Component\Console\Output\OutputInterface $output) must be compatible with Symfony\Component\Console\Command\Command::execute(Symfony\Component\Console\Input\InputInterface $input, Symfony\Component\Console\Output\OutputInterface $output): int in <b>/var/www/html/vendor/porthd/timer/Classes/Command/UpdateTimerCommand.php</b> on line <b>149</b><br />

In a classic installation I get the following error, when I try to use the database analyzer to correct the install error:
