Some service probably shared, running unit to target test class got correct result:

vendor/bin/phpunit /Users/samsonasik/www/rector-src/rules-tests/TypeDeclaration/Rector/ClassMethod/ParamTypeByMethodCallTypeRector/ParamTypeByMethodCallTypeRectorTest.php
PHPUnit 10.5.27 by Sebastian Bergmann and contributors.

Runtime:       PHP 8.3.4
Configuration: /Users/samsonasik/www/rector-src/phpunit.xml

OK (18 tests, 19 assertions)

Run all test got error:
