How to run BeamMP when Userpath has been changed?

Same as here: Trouble, cannot play BeamMP with any form of mods

I’ve moved my Userpath in the startup.ini. BeamMP keeps dumping stuff into AppData\Local\BeamNG.drive.

I don’t want to have to use a symbolic link.

Hello, here’s a development launcher that checks startup.ini for a userfolder location: https://github.com/BeamMP/BeamMP-Launcher/actions/runs/14846936477/artifacts/3065764417.
