Same in Graphql module when I try to test on PHP 8.2 https://github.com/drupal-graphql/graphql/actions/runs/4076491036/jobs/7024295853

Workaround: remove the stub class:

if [[ ${{ matrix.phpstan }} == "1" ]]; then rm vendor/mglaman/phpstan-drupal/stubs/Drupal/Core/Field/FieldItemList.stub && cd modules/graphql && ../../vendor/bin/phpstan analyse; fi

I Have same errors. As I see, it's related to this PR https://github.com/mglaman/phpstan-drupal/pull/505/files
For now, I've downgraded to 1.1.27 and these errors have gone.

Merged PR fixing the stub files, and now we have a test to validate them to prevent this from happening again. I'll be tagging a new release with this fix shortly.
