Currently, PHP 8.1.10 is stable, and the library https://github.com/googleapis/google-api-php-client within your plugin is old and problematic.

Not sure which release this was tested on but release 2.2.0 (DATE: AUG 21, 2022) added "PHP 8.0 & 8.1 compatibility" per the changelog. There's been more changes since then so feel free to test again with the latest but please note which version if you do find further issues. Thanks.
