I don’t see an error like that in our source code.
Does this happen consistently or did it happen more than once? If so, could you please report a bug? I’d like us to take a look at what’s happening.

It happened 2-3 times so far.
If it will happen I will post more info here.
Meanwhile I will make a bug report and add link to this topic.
Also, this error was not crashing editor.
I will post bug number here.

CASE IN-87426
Bug reporter was demanding to wtite elaborate description so I had to write stupid long
text, which was not enough, so I added some bad jokes written by AI.
I hope this will not cause any problems :smiley:

and so on…
I find Unity 6 WAY more unstable than any other previous version. WAY MORE.
Also lots of crashes during Adaptive probes / lightmap calculation.
The moment I am in, is I always save the level before pressing “calculate” as nobody knows what might happen.
And the “funnier” thing above all those issues, is they are all gone after engine restart.
