insufficient memory in 2.8.0

[Alsafi]

Description of the bug

The problem is that an error is appearing saying that I don't have enough memory space, but with the task manager open, the memory doesn't exceed 40%

I hope you can resolve this soon, if not, I'll move to 2.7

Project file & How to reproduce

the error is in Portuguese

@tpihl, How did you confirm this issue? just tested attached 3mf? Or do you have your own case?

@Alsafi, How did you make your 3mf? Did you add tool changes, when your printer profile contained 6 extruder and then decrease count of them?

[Alsafi]

@YuSanka to be more exact, I got a 3mf that worked and had 6 extruders, then I deleted the keychain on it and added this one from the 3mf, I then changed the colors and sliced ​​it, then I got this error, then removing the extruders and leaving 1 turn on the normal, then putting it back to 6 the error happens again.
I tested it again now and the error happens

Perfect! So, we reproduced your issue correctly :) Fix will be a part of next release.

I use my gaming rig also for slicing and have ran out of memory several times where windows reports majority of memory free. Monstley with several complex model on the xl plate when I have copied some models to try different ways to place them (so I hide the currently non relevant copies to see what the time/usage/warnings and similar would be)

Fixed in 2.8.1-rc1. Closing.
