Rack 2.0.6 won't launch on brand new laptop - Fatal signal 22

I have a brand new laptop running Windows 11 Pro version 21H2 build 22000.613.

I installed Rack 2 Free, and attempted to launch it. Nothing happens. Going to the Documents/Rack2 directory shows only one file, log. Contents of this file:

The computer I am using is a Lenovo ThinkBook 13s Gen 3. One of the first things I did after setting this PC up was uninstall OneDrive, so I don’t think that’s the issue. (I had read about that being a problem for some people.)

Oh my, I just wasted hours and hours trying to fix this problem. I thought 2.0.6 was the latest version, because that’s what’s linked from https://vcvrack.com/rack#get. I was at the point of giving up on 2.0.6 to try an older version, when I found https://vcvrack.com/downloads and saw that the latest version is actually 2.1.0! I installed that and it launched straight away!

VCV team really needs to update the download link for VCV free!

2.1.0 is in preview, it is not actually the current release.

Since you’re on Win11, and since Rack v2.1.0 contains “Update to RtAudio 5.2.0”, I’m taking a wild guess that the newer RtAudio version is needed for properly supporting Win11 with all driver types and audio hardware. Of course to confirm that theory other Win11 users need to pipe up and let us know if Rack v2.0.6 works for them, and with what drivers and what audio devices.

2.06 is working fine for me on Win11 - Focusrite USB ASIO on a Scarlett 2i2

yeah, me too. Although with 2.0.6 I crash in RTaudio if I turn off my interfece while running , and that doesn’t happen with 2.1.0. So maybe “the updated rt audio improves support for some audio devices”?
