Unknown Compiler errors at start for every new project

Hey Everyone!

So for some reason, after switching to unity 2018 (pretty sure it's the latest one) from unity 2017, starting tutorials/projects have been a bit frustrating.

Everytime I start a project/tutorial, a set of compiler errors appear on the console. I haven't added any scripts and when I attempt to run the empty project/tutorial, it prompts "All Compiler errors have to be fixed before you can enter playmode!".

The attached are the pictures of the errors, one without build and run and the other with build and run. I would love to provide more information if it's necessary to fix this issue!
