Hello.
This usually shows that the version of openCore you are using does not match the one the config.plist was written for. The error shows you in which sections the missing parts are: Misc / Debug and Misc / Security.
Depending on how you edited your config.plist you will need to add or remove the keys. If using OpenCore Configurator you must ensure the version matches the OpenCore release.
Sometimes just removing the keys if they are in your config.plist will solve the problem.
What you should do before trying another reboot is to use the OpenCore "ocvalidate' Terminal app to check your work. From the OpenCore release package drag the ocvalidate app from the Utilities folder onto your Terminal window. Then drag and adrop your edited config.plist onto the same line, and press Enter. This will check the file and highlight any errors found.
