Issues since upgrading from EE7.5.15 and still on Cartthrob 9.0.0-b.1

Since upgrading from 7.5.15 and still on Cartthrob 9.0.0-b.1, seeing the odd error like this:

```
SQLSTATE[40001]: Serialization failure: 1213 Deadlock found when trying to get lock; try restarting transaction:
DELETE `exp_cartthrob_cart` FROM `exp_cartthrob_cart` LEFT OUTER JOIN `exp_cartthrob_sessions` ON `exp_cartthrob_cart`.`id` = `exp_cartthrob_sessions`.`cart_id` WHERE `exp_cartthrob_sessions`.`cart_id` IS NULL
```

Also hoping there has been some movement on CT since I installed this version?

On a side note, does EE offer the option to stick cleanup functionality into a cron job? Seems like CT cart cleanup would be one of those cron tasks.

EE: 7.5.17
MariaDB: 10.11.13
PHP: 8.2
