I think the issue that you're talking about, that was fixed, is unrelated to the problem you are seeing.
Please go through the guide I linked in my previous reply which has suggestions on narrowing down the cause of any crash that happens when changing folders.
Until we know what is triggering the crash -- and it's usually a particular file that you have in one of those directories, which triggers a bug in either Opus itself or in 3rd party software that runs inside of Opus (e.g. shell extensions, video codecs, anti-virus...) -- we cannot do much about it because it's so far only happening on your machine.
Also, see if any crash dump files have been created. If you send those to us they will sometimes (not always) indicate which component the crash is happening inside.
