For players who are having the same error i had after 3/24/21 [sage] update
1)Open registry editor
now copy this and paste it at the path adress at the top of the registry's editor
HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\User Shell Folders
2) Now find the file name that says Personal
3) Select and Rename the path of the file
From : c:\Users\Yourusername\Onedrive\Documents to c:\Users\Yourusername\Documents
you do not need to restart your PC unless you need to or it's not effective
I hope it helps for some players
I already sent a ticket earlier for support but this is annoying because your settings will revert to default every log-in
in my case, my path already look like solution you gave..but still same error still happen.
Maybe it has something to do with your anti-virus when i started my game avast detected it like a virus because BDO is going change the file GameOption.txt and click "allow app"
erm..yes im using avast also..but i dont received any detection when started bdo.so i should turn off avast or what?sorry..noob xD
Edit : ok problem solved..had to turn off avast =="
