Shakaran,
Sorry that you are seeing this issue.
Thank you for sharing the config logs and error details. We have issues with Bread Crumb tool bar in pre-release builds of 4.13.
Can you please update to the release build of 4.13 and then check? If it still throws the error, then please uninstall and reinstall DevStyle and check.
Apologies for inconvenience caused. Let us know how you get on with it.
