Animation_nodes: Saving Sound Spectrum Node crashes AN 2.1.4/2.1.5 in Blender 2.80.75

[baudouin-hub]

I'm running Windows 10 64bit and Blender 2.80.75, trying to install 2.1.5 but i'm getting the following error. Tried installing on 2.81, same story. Manually deleted old AN installation directories etc.

I tried installing 2.1.5 because I was trying to set up a small sound reaction system, which works up until the point to where I save the file. As soon as I save I get a general execution error that remains until I reboot Blender a couple of times.

Thanks for the report! We will look into it.

Little update: so I managed to get 2.1.5 running: https://blender.community/c/graphicall/ffbbbc/ < that version. But the problem I have with the sound nodes remain. It all works fine up until the point where I save the setup.

@baudouin-hub Are your sounds packed in the blend file or read from a file on disk?

[baudouin-hub]

Not exactly sure if I do one or the other. The MP3 is loaded from a file on disk within the sound spectrum node. This way it is also saved into a blend file. Seems like it is in this file since it is larger then a usual blend file. I stripped away all the other nodes and experimented with just the sound spectrum node and I can confirm that the problem is there, not in the further setup of nodes.

[OmarEmaraDev]

Ok. I just replicated the issue. It seems it happens when the sounds are packed. The AUD sound object is none when the sound is packed, seems to be a Blender bug.

[OmarEmaraDev]

Fixed in e48ac04.

[baudouin-hub]

Thanks!

@baudouin-hub The original error you reported can be fixed by installing vc_redist.x64 from microsoft's support center.
