System Information
Operating system: Windows 11 Pro
Graphics card: Nvidia RTX 4090

Blender Version
Broken: 4.0. 4.1.1
Worked: -

When trying to open blender save from quick select on splash screen and during load end task in Task manager. On subsequent run discarded splash screen and used File->Open. Blender crashed and would not open again. Running blender once more will cause brief full screen flash and then nothing. I have a slow NAS, I mistakenly clicked on large save file form that NAS. Wanted to quickly exit as blender is not responding during the load and then open other file. Something similar happens when system can not connect to NAS, but not always. Also similar thing happens when not using NAS but at random when opening saves from File -> Open. I archive my pas projects on large HDD with Windows file compression turned on.

Only thing that fixes the problem is to restart Windows or log out and then log in. Same happened when I was using Windows 10.

Steps to reproduce:

Mound Windows network drive using SMB 1.0. By default it should be Z:\.
Save blender file to the attached drive.
Open blender again.
Select blender file from splash screen.
End Blender task in Windows Task Manager before file finishes loading.
Open blender again, try opening blender file using File -> Open.
Blender crashes.
Blender won't run.

I am personally unable to reproduce the issue on my computer. Although I used Windows default SMB version which probably isn't 1.0, and I'm on Windows 11 Home, not pro. Although I'm doubtful these have an impact.

Can you collect debug logs for us? To do this, navigate to the folder where Blender is installed, then run blender_debug_log.cmd. Blender should hopefully crash instantly, and you will see a folder with some files. Can you share the file blender_debug_output.txt with us?

Once you've done that, we can look into seeing if we can fix the issue without any code changes.
Based on the steps to reproduce, and the symptoms, I would take a guess that the Recent files list is corrupt. Can you try deleting the Recent Files list and seeing if that helps? To do this:

Navigate to C:\Users\YOU\AppData\Roaming\Blender Foundation\Blender\4.1\config\
Delete the file called recent-files.txt Then try opening Blender.

If that doesn't work, then my second guess would be something broken with a add-on. Can you try opening Blender with factory settings? You can do this by:

Navigate to C:\Users\YOU\AppData\Roaming\Blender Foundation\Blender\
Rename the 4.1 folder to something like 4.1-backup

or

Navigate to where Blender is installed.
Run the file called blender_factory_startup.cmd

If that doesn't work, then my next two suggestion is to turn your computer off and on again, and if that doesn't work, then re-download Blender just in case Blender became corrupt somehow.

It's empty.

I've attached a video of me trying to generate this log.

I couldn't reproduce this bug myself again. As I wrote earlier it happens at random. While recording of the bug I have other instance of Blender running, it's rendering and working just fine. I though I finally had it pinpointed, because it's driving me crazy.

Just to reiterate:

Bugs like this happened before on multiple versions of blender at random, different GPUs and on Windows 10 and 11. I wasn't able to pinpoint the problem.
The bug reported here can't be reproduced by me when trying to respond with more information for @Alaska.
I started doing other things and ran animation render (which is still going). Tried to open another instance of Blender but the bug happened.
Happy that it happened again, because I can submit log.
Log i empty :/

Just confirming.

You say this issue happens at random. As in, if you force close Blender while opening a file, this issue sometimes happens and sometimes doesn't? Or just in general, sometimes this issue occurs and sometimes it doesn't, it doesn't matter how you close Blender? How often does it occur?

And rebooting your computer fixes the issue?

You say this happens across multiple Blender versions, Windows versions and GPUs. Are you using the same computer for every test? Or different computers?

Do you have a 13th gen or 14th gen Intel CPU? Apparently some of the high end CPUs from those generations are having stability issues, and BIOS updates are being issued to fix it. I don't think this is the problem you're having, but it's possible.

Yes, It started after 4.0 release. I tried different things to consistently recreate the bug. But it always happens "at random". However it happens more often when I have one blender instance opened and want to open another one at the same time.

Rebooting the computer or logging out and back in fixes the problem.

@MrJW ^

It seems blender is not opening after the crash. Could it be some anti-virus software preventing blender to launch? Do you have any?

I have Ryzen 9 5950x. I'm using Eset Internet Security, but previously I was using Windows Defender.

If it where the antivirus, then blender would not start at all.

@MrJW I generally agree with you, Blender probably wouldn't open at all if the issue was with a anti-virus. But maybe the anti-virus sees Blender as "safe", then makes it as "unsafe" once it does something weird (E.g. A addon trying to modify a file or access the internet). And when you reboot or log out and in again, the anti-virus resets Blender's level to safe again? So the next time you run into this issue, can you try disabling your anti-virus and seeing if it help? And report back with the results.

@MrJW Do you have a drawing tablet? It has been brought up a developer that the issue might be a issue with the drivers for your tablet, which then lead to issues with Blender.

Also, the next time you encounter the issue, can you open a command prompt and run this command and share the output with us?
/path/to/blender.exe -t 1 --log "*" --log-level -1

I have, but I just installed Windows 11, I didn't even install drivers for it yet.
