The Library folder contains the imported data that makes up your project.
All of this data is generated from the assets and code, and can be removed and regenerated.
Start by regenerating the script assemblies, if that doesn't work regenerate the complete project.
Deleting the ScriptAssemblies folder will reset most code-related issues, and only requires a partial project reimport.
Deleting the Library folder will reset all imported code and assets, requiring a full project reimport. This can take a long time for projects with many assets.
