Hi Doug,
Yes... I can confirm that this crash is happening here too after updating.
I also passed my crash log on to the PG folks, so hopefully they will have it sorted before too long.

In the mean time, I was able to extract the previous version of the plugin from the build 703 package and replace the 704 build one with it.
Logic works fine here with the older build.

If you are unsure on how to extract individual files from packages, I used this free tool. it works very well.

hopefully this helps !
