I wanted to start speedrunning portal again and in-game I noticed that the autosplitter was not activated but when I tried to activate it there were two different error messages coming up. either "The Auto Splitter could not be activated. (An item with the same key has already been added" or "The Auto Splitter could not be activated. (Object reference not set to an instance of an object)". So far I have found someone with the same problem but no solutions. I would really appreciate if someone could help me in any way.
