Exporting group track named "Aux" stalls the audio mixdown


This seems very weird and specific, but in Cubase 12.0.20 if I name a group track exactly “Aux” and select it in Audio Mixdown export, the render stalls at 1 or 2%. It seems to eventually succeed, but it takes hours and results in “disk overload during export” in the end.

I’m able to reliably reproduce it even in an empty project, on my system in Cubase 12.0.20. When I rename it to literally anything else, it seems to render fine. Not sure if it’s intentional - I couldn’t find anything about this in the manual.
