Can anyone help? Today I've made a mistake in some way and now I cant fix it, where the whole problem is about the mod issue that is popping up every single time when I am trying to set up the folder for mods to download in Vortex. The message say "You need to select directories that the current user account can write to". What should I do? Because I am completly lost, I've tried many ways to try to fix it.
