Short description of error
I don't know what to do when I open this file and it flashes. Every time I save a file, it looks like this, it can't be opened
Exact steps for others to reproduce the error
What do you mean by flashing? Can you open the file you attached? Or is it already "corrupted"?
Yes, I tried many other ways to open, and then found a way to open, that is, in the blender.exe directory using blender_debug_log.cmd start, so you can open, but I do not know why this is so, I tried to copy the contents of the Blender file into another file is possible open
是的,我尝试了很多其它打开方式,然后找到了一种方法可以打开,就是在 blender.exe的目录下使用blender_debug_log.cmd启动,这样就可以打开了,但是我不知道为什么会这样,我尝试了将这个Blender文件里面的内容复制到另一个文件内是可以正常打开的
When you run blender_debug_log.cmd (see blender directory), upload the two files it mentions here.
I tried to copy the contents of the Blender file into another file is possible open
Not sure what this means, so the issue is gone when pasting the content of 20.blend into a blank file?
I can only append the last two collections, all others result in an exception in OpenSubDiv code. I would assume this is caused by a corrupted mesh.

If you can, please provide instruction that resulted in this broken file. It's unlikely that we are able to find the source of the problem from the broken file alone.
@EMM (IMBI) Could you please check if you are able to provide instructions that result in the broken object?
It may be because I put it on a portable hard disk to use, the hard disk is a little damaged during use, but this file has been recovered, I use blender_debug_log.cmd to open the BLENDER and then append the file to retrieve the
This is the only case I can think of, but I still can't figure out why it can't be opened directly and requires a DEBUG to open.
可能是因为我放在移动硬盘上使用,在使用的时候硬盘有点损坏了,但是这个文件已经找回了,我使用blender_debug_log.cmd打开BLENDER然后进行追加文件找回的
我能想到的情况只有这个了,但是我还是想不通,为什么不能直接打开,需要开启DEBUG才能打开
I'm not sure if the issue at hand could be explained by a corruption of the file by the damaged hard driver. I can't open the file without getting an exception including with the debug flags set and unless we know how to recreate the issue if it wasn't the faulty hard drive, then we can't really investigate this issue. Therefore, I'm closing this ticket.
Please create a new ticket or leave a comment if you're able to identify/recreate the problem.
