Same just happened to me:
java.lang.IllegalArgumentException: Cannot set property ayi{name=axis, clazz=class dv, values=[X, Y, Z]} as it does not exist!
fairly self explanatory. I have tried oak, birch, and darkoak logs in a variety of orientations. I am able to harvest the logs from trees, but cannot place them. The logs can be turned into planks and the planks placed. Trying to place logs causes immediate crash to the "crash report" tab of the launcher window.
Here is the important part of the crash report.
