It's an issue that we'll fix soon, please follow [https://github.com/elastic/kibana/issues/25728](https://github.com/elastic/kibana/issues/25728) to know when this is fixed.

For now you either need to enable reporting or disable canvas ([Error: Module not found error on 6.5.0 upgrade](https://discuss.elastic.co/t/error-module-not-found-error-on-6-5-0-upgrade/156845/4?u=azasypkin)).

Best,  
Oleg
