Short description of error
when i open second blender with another project the first blender crashes
Exact steps for others to reproduce the error
[Please describe the exact steps needed to reproduce the issue]
[Based on the default startup or an attached .blend file (as simple as possible)]

Does it give you a warning about saving the project ?
No any warings. Two blenders are just waiting for the next one to load the project through. And as soon as the project loads, the pre-opened blender drops immediately.

This is likely caused by limited system resources.
I've just tried different options.
Just to make sure, an edited* default startup file, right ? *:just clicking in viewport makes it so.
yes, I've edited startup file. Bleder doesn't crash with it. I've just finded out when I disable some layers (pressed the exclude from View Layer) and this simplifies the scene blender is stable

Let me see if I understand. You have an edited startup that when used, makes the blender crash if another project is open. Right?
In this case we need your startup file to try to reproduce the problem.
Blender doesn't crash with my start up file, it does when i open two heavy scenes. Can I send you both?
both files have less than 2GB
It is not practical for us to investigate large files.
We require the bug reporter to narrow down the problem.
Normally .blend files can be simplified by removing most objects and disabling settings, until the problem reveals itself more clearly.
As far as I understand the reason just in a large amount of information. How practically you can solve the problem without having heavy files. and how can the problem reveal itself? Unless I'm doing another project that will gradually increase beyond the critical limit and this will be an indicator for me, but it will be just for me. I think it would be more right for developers to know this limit of the scene to crash

So this indicates that the problem is because Blender ran out of memory.
While we want to improve Blender to handle such cases memory gracefully, this is not currently considered a bug.
We are aware of problems like this, so closing the report for now.
The fact is that in Beta this problem was not and everything worked stable. The next day I downloaded the official version and the fun began. There're 80GB of RAM in my pc, except for not enough of video memory

Okay so, but we need a file to reproduce the problem.
Guys sorry i disturb you i dont know what happened but the problem disappeared. Crash does not occur, instead the Material Preview mode simply does not work. I have a guess that the problem is still in the video memory, but I can live with it until the problem reveals itself much more ;-) Thank you for your attention and patience :-)
Material preview/ material shading with eevee is indeed a problem... keep cycles as render engine.
