Short description of error
crash when I open a file

Exact steps for others to reproduce the error
the file did not open for me. i used this help
https://developer.blender.org/T86300#1128503

After rebuilding I am working in Scene. 001 I saved this project under a different name and continued working. Blender crashed several times and today I again cannot open the project !!!! I try to open the scene 001 through append, but the blender collapses. I'm in a panic and I'm disappointed.

the file did not open for me

The steps I gave in that report won't fix the file. The steps allow you to Append the file into the default startup file, then the script tries to fix the corrupted meshes in "Scene.001". You would have to then save out the data yourself.
If the scene you append is not called Scene then you don't want to use that script. This one is a bit more generalized:

import bpy
for obj in bpy.data.objects:
    if obj.type == "MESH" and obj.data is not None:
        if obj.data.validate(verbose=True):
            print(f"Error found: object {obj.name} had invalid mesh data!")

Let me know if this works.

Since not much time has passed since the last corruption, this might be a chance to try to figure out what might be the cause.

@Dmitry13 : can you describe what you have done with Cylinder.003?
What I mean is: what modeling tools do you use? Extrude Manifold? please try to remember each tool used here.
The object has not been imported, right? If it was: which importer/format?
It is also interesting which tool options you used, for example, was this turned ON?

Did you use modifiers (and applied them)? which ones?

I have simple shapes, I make icons. the problem was that I copied an object from another project to a new project that "broke". This item has not been checked.
Now I have restored everything manually and will continue to be attentive. Thank!

This means {key Ctrl C} in one instance of blender and {key Ctrl V} in another instance of blender, right?
Were these the same versions of blender? Both 2.92? If not: which versions were involved?
Could you share the .blend file were you pasted from? which object?

This information would really help quite a lot, thx in advance!

Это означает + в одном экземпляре блендера и + в другом экземпляре блендера, верно?

YES!

Cannot spot issue when copy-pasting.

So we are still hunting the cause of the corruption.
Now the most interesting part would be to figure out:

are (modeling, UV) Addons involved possibly?
which belender native tools were used?

(btw. if you having problems with appending scenes that have corruptions, then you might try a fresh 2.93 build from https://builder.blender.org/download/, this has a fix for #85947 (objects from appended scenes are added to current scene as well (if they are directly under the Scene Collection in the source file)) and thus will not pull your corrupted mesh into your current scene -- which in turn would crash)

I didn’t use any add-ons in icon design. I don't have anything from third-party plugins. I recently started to study the blender and use exclusively all the native tools for changing the geometry.

But the problem I had only when I copied.
By the way, in the scene with the safe, I later made corrections and ungrouped the elements. Sorry, I forgot completely =)
I'll try a new build. Thank!

Thx getting back.

OK, good to know

By the way, in the scene with the safe, I later made corrections and ungrouped the elements. Sorry, I forgot completely =)

does this mean the safe.blend file posted here is not the causing problems anymore?
with ungrouped the elements do you simply mean in terms of collections? parenting? or is separating meshes involved? like Mesh > Separate > Selection / Material / Loose Parts ?

I don't understand what is happening at all = (
The file that I restored manually (((( does not open again and the blender collapses
backicon.blend

command+j I combine the shapes like this
and I separate it like this, I go into the edit mod, select what I need to separate and press P → Selection

opened with a script. did not find any damaged mesh.

OK, I have the feeling we are getting closer.

Trying to reproduce this (still cant):
Which parts were joined, and then which parts were separated?
(in backicon.blend the Cube.006 mesh is now corrupted)

and here it is again! )))) I worked, went to have lunch, but I tried to do something as the program crashed (it always happens) and I can no longer open the file.

I separated the door at the safe. The doors had hinges, a lock and a steering wheel

icons.blend1

здесь коллекция INVEST приводит к сбою программы. все в этой коллекции сделано с нуля! Я ничего не копировал. Это конечно очень печально! Сожалею, что начал изучать блендер ... Худший опыт в моей жизни!

sad to hear, I will try to investigate more on this separating issue (but still wasnt able to reproduce)

Blender also collapses after a long inactivity and the project that was opened can be damaged after the collapse. This is not the first time this has happened to me.

incredible horror and not a program !!! crashes and destroys individual meshes inside. SUCKS !!!

Still trying to help.
(think we could tone down the language though, no? swearing is not how we talk to each other around here...)

regarding https://www.dropbox.com/s/z4qqynlexjjemb3/Blender%202021-03-16%2017-37-31.png:

Could you share that file as well? (this could have different causes, just display options, it could be a mesh without faces, this is just hard to tell from a distance...)

Terribly sorry, but since we cannot really put together a recipe for reproduction steps, this will have to be archived for now.
