Don't understands... maybe because of Drupal or php?

I was unable to repeat this problem with Drupal 9.5.11 and PHP 8.1.18. But everyone who has encountered the issue can try flush caches, uninstall and install the module again. If that doesn't help, this patch will be a good solution.

On Drupal version: 10.2.3, MariaDB version: 10.4, and PHP version: 8.1, everything is working fine. I was able to reproduce the error on Drupal version 9.5.0, but the patch from @shashank5563 successfully resolves it.

I tested the patch from @shashank5563 on Drupal 9.5.11. The error has disappeared.
