I frequently get an access violation message, whenever I a): launch BIAB from the desktop, or b): try too many styles when working with a song.

This is some of the message:

An exception error has occurred. You can continue to use the program, but should likely save your work and reboot program.

Access violation at address 0065F7B4 in module 'bbw.exe'. Read of address 00000369.

This happens randomly but more often than not, and has done so sine I started with BIAB 2018.

I have 2019 Ultrapak with the latest build 509. I have audio driver as MME.


I have a Steinberg ur22 audio interface. The error occurs whether or not I have the interface usb connected.

I have put up with this as a slight annoyance, ala Monty Python, but would be interested in any thoughts about how to be rid of this bug.
