My game works... relatively fine, it has crashed once but it aint too big a deal. that being said however, i cannot save my game; whenever i go to do so, i get the message "save failed"

Can someone help me solve this issue?

Erm... Should be saved to the path
\%USERPROFILE%\Documents\My Games\Driver Parallel Lines\
without issues...

I have checked that, so far i have gotten some saves from the internet, however, beforehand, there was nothing. Even now, i cannot properly save my game onto the profiles i have gotten from the internet, as i will receive the same message.

Galaxy or offline build?
Enable read only on my games fodler and then turn it of. Try to start game or galaxy (if you use it, it also apply to game) as admin.

Remove game folder from My Documents and let game create it again (start new game).
Try to reinstall (start installer as admin) game to differ folder - like ' D:\Games\Driver-Parallel\ '. Same for GOG Galaxy and galaxy build. But for galaxy - do verify installation next after downloading. Better twice in a row, since Galaxy always redownloadd something and do not report what exactly.

Install galaxy\games to X:\Games\ is not turn off antiviruss. Starting exe as admin do more (for standart Defender at least), but still security apps continue work. Defender should be ok if it is not program files and admin-run exe. Any else security apps try to turn them off or manually add all games-folders (for game and for galaxy) to exeptions.
