Europe doesn’t use the same credit history system as the US; so yes, it quite literally is a different planet in that sense and you quite literally can start new. This is not financial advice.
My understanding is you can absolutely end up with a lien and other such things, so it wouldn’t be a good idea unless you’re ready to burn every financial bridge with the US for the foreseeable future. But if you’re not coming back, then that’s that I guess.
