The offending character is probably only the blank after the hyphen.
Try to rename the original folder in Google Drive, because in Windows no app will be able to create file name and folder with trailing blank.

I can't because it's a shared folder and I'm not an adm.
I think FreeFileSync can't use long file names...
But the real name of the folder, or folders, are larger than freefilesync told us.
Don't have this name here.
I have more than 1 folder that exist with this initial.
