No bug... just inexperienced user.
You need a driving license just to join traffic with a car and years of experience to race with Koenigsegg on a track.
Crash is caused by applying displacement material on procedural modifier... put it on an object! Add Light! Render.
hahaha you made me laugh with such crap you wrote.
I am not to blame for you not being able to understand the problem description, then I invite you again to read the initial message.
Do this and then come back here again with his unfortunate irony, I allow you.
But the condition is you give me a file that works. It is no use applying displacement in the wrong object and try to teach me how to drive, because this way you are shaming yourself again.
If you need help I can record a tutorial.
I will not be polite again.
