Layer seperation

[Oilipuu]

Using N2 printer, set back to default, then it started to print weirdly, enclosed pics. When it starts up it skips laying down filament. Any suggestions

Would you like to advise what type/brand of filament you are using?
Whether you are printing with top cover on or off?
Would you like to share some pictures around your hotends and nozzles?
Please double confirm whether both of your cooling fans are running non-stop or not.
