Hi, I noticed this issue today, and I will try to provide a repro;
It may be similir to some other same issues reported but I’m just going to start a fresh one as I’m on latest 11.0.10
The issue seems minor but until I figured it out, it persisted through reboots (win 10)
1 -Create a project when the Record location (project location) will be on a very nearly full drive.
2- create virtual instrument (midi) part and render it (standard settings, Dry output ) disk should be full - error message will appear
3-You can remove space from your drive but you will still get the error message, even if you reboot, UNTIL you reselect your Render location - in ‘Render In Place Settings’ - File Location.
