Export with custom mix but more than 8 tracks

Hello, im trying to export a .ogg file with custom mix, it has 13 tracks.
When im exporting it and trying to play it, it doesn’t play anything on VLC Player, on the browser it just stops at 0 seconds.
I tested around and found out that it only works if i use 8 tracks or less.
Is it possible to use more than 8 tracks when exporting it as .ogg, if yes, how?
If you got a fix please tell me so i can continue with my project.

Perhaps VLC supports a maximum of 8 channels.
Do you have a playback system with more than 8 channels?

Try importing the file back into Audacity - do you get the correct number of channels?
