I encountered the same issue after upgrading the core and contrib. However, switching from beta to dev fixed the issue for me.
`composer require 'drupal/commerce_price_rule:1.x-dev#33649e2'`
When Drupal core and commerce modules were updated, we started to get this error when trying to do any action related to a purchase.
Error showed up in logs is:
Error: Call to a member function dispatch() on null in Drupal\commerce_price_rule\PriceRuleStorage->loadAvailable() (line 131 of /modules/contrib/commerce_price_rule/src/PriceRuleStorage.php)
