I tried opening a workspace that another user created on my mac. The permission was not set correctly and it was put as readonly. When that happens you get to a state where you cannot change the workspace again.
If the user is not in the condition to change the directory they selected then it will be impossible to recover from this situation.
See attachment for error.
Instead, an error should pop up as it does now, and then the workspace selector should pop up again. (note: I've selected to never ask me again on startup)
