Error Copying Behavior Tree

Edit: I saw in one of the other posts, Jason's suggestion to change to save as JSON. This fixed my issue. I am leaving this here in case it helps someone else.

I am getting a crash when trying to create a new Behavior tree based on the FirstPersonShooter Scene.

I exported the Behavior tree from the demo scene. Initially I tried to copy the entire tree into the new tree, but this failed with errors and trees dissapearing. So now I am trying to copy one branch at a time. I consistently get the below error and the copied sections disappear from the new tree.

My Exported tree also stops working. And I cant open it after a while. Restarting Unity does not recover the issue with the exported tree. The file is there, but I continue to get the below errors.

My Environment:
I am using version 2020.1.3f1 Personal. With Version 1.6.5 of Behavior Designer and Version 2.2.5 of Ultimate Character Controller, together with the Behavior Designer Movement Pack. Patched version of Windows 10.

All the demos were downloaded from the Opsive website in the last 24 hours.

If anyone has had same issue and found a fix, please let me know what that is.

Thx.
