3.6.0 upgrade throwing error

Hi!

We are running a hosted WP instance with the following details:

• WordPress version 6.8.3
• Active theme: Deborah (version 1.3.13)
• Current plugin: Simple Calendar (version 3.6.0)
• PHP version 8.2.29

Yesterday, after the plugin auto updated from 3.5.9 to 3.6.0, I got an email notification from WP about a fatal error that causes the calendar page to not load. Here are the details:

An error of type E_ERROR was caused in line 169 of the file /dom758201/wp-content/plugins/google-calendar-events/third-party/google/apiclient/src/Client.php. Error message: Uncaught Error: Class "SimpleCalendar\plugin_deps\Google\Auth\GetUniverseDomainInterface" not found in /dom758201/wp-content/plugins/google-calendar-events/third-party/google/apiclient/src/Client.php:169

Any idea what may be happening here, or how I can resolve this?

Thanks
