Cannot access the game's files

I recently got a new computer and after installing the game on the computer, I can no longer accses any files. The usual way documents> beamng drive> moved here, no longer works and I get an error message. I can still see most of my mods in the game and use them without issue, a few mods are missing though. No problem with the mods manager in game, it's only the actual files I can't get to.

This is the error that came up. I've tried going different ways but it keeps giving me this message
