Olá,
Ao tentar instalar o PHPUnit com o comando composer install ou composer update ocorre falha nos pacotes phpunit/phpunit e phpunit/php-code-coverage e é retornado os seguintes erros:
Install of phpunit/php-code-coverage failed
Install of phpunit/phpunit failed
Failed to execute git checkout be1fe461fdc917de2a29a452ccf2657d325b443d -- && git reset --hard be1fe461fdc917de2a29a452ccf2657d325b443d --
HEAD is now at be1fe461 Prepare release

It looks like the commit hash is not available in the repository, maybe the tag was recreated? Run "composer update phpunit/php-code-coverage" to resolve this.
Já tentei rodar o comando que é sugerido na mensagem e mesmo assim não funcionou. Estou utilizando o php na versão 8.2.8 e o arquivo composer.json esta com o require do php >=7.3 e o phpunit ^10.0.
