Error
whenever i open the file it crashes without displaying an error screen. Its an 11 minute video clip consisting of videos (i made proxies for all of them) images and audio files(voice and background music). its fairly simple, less than 20 000 frames (30fps). I'm new with video editing and that took me a very long time to make. So I hope you're able to help me restore it
I would also like to say that the program crashed fairly often before that, especially when i tried moving long audio clips and adding cross transitions. i got around that by saving every 10 seconds which, annoying as it was, didnt stop me from doing my job. The video was just about finished when it crashed for the last time (and i havent been able to open it since).
Try to open the file

Can you try opening the file in 2.83. https://builder.blender.org/download/
Can you please provide the
system-info.txt
file that is created withHelp -> Save System Info
Yes, i downloaded 2.83 just now and theres still the same issue. File immediately crashes when opened
system-info.txt
Added subscriber: @ankitm
Could you reliably make another file that crashes like this ?
Please add steps to do so with relevant media files. It would be better if it is confirmed after that.
File crashes when startedto Program crashes when editing a video file, corrupted it.im sorry i really dont know how to do that and that ( #0 in direct_link_scene at source/blender/blenloader/intern/readfile.c:6969
3 in blo_read_file_internal at source/blender/blenloader/intern/readfile.c:10410...)
means total gibberish to me. i dont really know what makes it crash so i cant really make another file that crashes in the same way. But as i said the program would crash fairly often even before this final crash even with other videos that i tried to edit. But despit those crashes i was still able to ope the file afterwards. And this time i cant. Im sorry if i dont make any sense, im trying to explain it to the best of my abilities
No worries. But if you come across some steps that can repeatedly crash Blender, do tell us.
Yes, it is for developers.
Yes you do; don't worry. :)
For recovery, best shot is the .blend1 file in the directory as the original one, or autosave files in %temp% directory.
Also check
C:\Users\brata\AppData\Roaming\Blender Foundation\Blender\2.83\autosave
C:\Users\brata\AppData\Local\Temp\blender

Thank you, that worked! You were really helpful and im amazed by how quickly your team responded! I wish you all the best and will keep you updated on any possible bugs i come across : )

@tristolin Thanks for report. Can you please upload also file that still works? Also can you try to remember what were you doing when Blender crashed?
It is worying that this is second corrupted .blend file for quite short time. Both from 2.82a with missing
seq->effectdata
. #75015 had corrupted speed effects.Will recover this file as well to see if there is any common denominator.
Unfortunately the same video now crashes by rendering. Should i make a separete Bug report or will you be able to answer my question here?
Im giving you my output properties, in case it helps{F8503947}
here is the blender file that does not crash when opened (although it does crash by rendering{F8503966}) i was either trying to move a big audio file (the background music) or adding a cross transition on the last image in the video. i cant remembr by which of these it was, but blender seemed to crash quite often whenever i did these

There is report for that issue #75822 (VSE: BLI_assert fails while rendering strip with changed font)
It is caused by using custom font in text strip. You can either use Blender 2.80 or 2.81 to render or use default font. Will fix this ASAP.
From what I can see here and in #75015 files had prefetching enabled. I think I have seen some nasty behavior when graph editor is open and strips are animated. Will have to investigate this.
In any case I can't really see mechanism how files can get corrupted.
@iss #76033 (Video Sequence Editor crash with prefetch and meta strips)
i was using the standard font in all of the text boxes, however rendering the video with 2.83 worked just fine (although it took almost 2 hours, dont know what the normal rendering speed is). anyway rendering on a different version solved my issue, thanks a lot
Having said that, I also need to make sure, prefetch is disaled during rendering. It has really bad impact on performance.
Shouldn't crash though.
I have found likely crash when creating undo step.
Main:
Prefetch:
I will need to understand undo system design a bit more to properly investigate.

Undo will change datablock pointers, freeing the previously used ones. If there is a dependency graph doing copy-on-write step in the separate thread you will have a race condition.
Easiest solution would be to stop prefetch job before undo, and resume it after (similar to viewport render, preview icons and so on).
Thanks for reference.
I am obviously stopping and reseting prefetch during undo, but I guess a bit too late.
So far I have found oddity that scene was created on different address than original scene was during undo, but that may be different/invalid issue.

While investigating this issue I have found and fixed 2 problems that may be related -

. I wasn't able to cause any data corruption, and exact cause is still unknown, but I will assume this issue is resolved.
