Hello troubleshooters,  
	I just installed the 9/2021 update and the new File - Export - Audio menu worked only once for me. Now when I click it, Bandlab holds up and nothing happens. Pressing Esc a few times will get me back to the regular functioning program. 
	I can get a simple export dialog and a successful export when I click the "Export" button in the Control Bar (Export - Audio - wav for example), but the program will also hold up if I try to click the "Advanced" option in its drop down menu. 
	Has anyone else experienced this bug? Any suggestions for a fix?  
	I'm running windows 10 
	Intel(R) Core(TM) i7-6700K CPU @ 4.00GHz   4.00 GHz 
	32gb RAM  
	Thanks.
