I'm getting this error, I incorrectly created an infinite loop and needed to cancel it so pressed escape. When I loaded the scene again, I got this error attached.
Nothing is visible in my scene on reload, and activating each node does nothing. It's like it wiped all my edits (curves/drawn masks)?
I am also getting this behaviour. Made me lose countless hours of work having to go back to previous backups to copy/paste curve nodes. Hard to reproduce so haven't been able to submit a proper bug report
