Are you sure you don't mean build 6021 or 6025? Build 6021 was released on 1 August 2019 to fix a crashing issue with build 6001 which was released back on 27 June. Build 6025 was released for MacOS on 30 September as a Catalina update.
Please see:

Please list your operating system version/build in any reports like this, as the issue is very often OS related. For Mac, it is the Apple menu > About this Mac. For Windows 10, type "About" in the search box - which should return About this PC - and press Enter. Under Windows specifications, you'll see the edition, version and OS build - provide all of them.
And, of course, on Monday if you don't have an answer from anyone here, contact your local Graphisoft tech support.
