System Information
Operating system: Windows 10
Graphics card: NVIDIA GEFORCE 1080ti

Blender Version
Broken: 3.4.1
Worked: (newest version of Blender that worked as expected)

Short description of error
Hi, sometimes blender crashes and I refer to the autoback file. It works but 50% of the time my creases I applied to other meshes are completely gone (edge and vertex creases). Its if as blender forgets to back those up for some reason. It cost me another 2 hours.
Exact steps for others to reproduce the error
Blender crashes->autoback file ->edge creases disappeared. heres the creases removed..

Hi, thanks for the report. Provided information is not sufficient to track the issue.
If I understood correctly, you are describing two separate issues, right?

Crash
Disappearance of edge crease
Do you remember the exact way to trigger the crash?
re edge crease issue: Did you ever save that file with edge creases? Or did you apply them recently? How much is the auto-save timer value?

Hi, I switched to blender recently so I cannot say if its a recent occurence.

Some more context. I work in blender on the model (linked above). However, sometimes it would crash, perhaps of heavy boolean operations combined with modifiers. Since I didn't save in some cases, I proceed to load the most recent auto save. It works and has fairly backed up most of the progress however the edge creases on my models are all gone. This happened quite a few times now on the same scen, and would sometimes only randomly happen to some objects (creases disappeared). This time, when I decided to make the bug report, I loaded again such autosave file and continued to work on the project. I had hidden all but one element, however when I unhid all the other elements, all my edge creases were gone (as shown in the image). Now, I cannot seem to reproduce it consistently. Again, this seems to happen sometimes, making it hard to reproduce on my side. The details about the scene and elements however is that i use edge creases with subdiv and booleans on alot of pieces. The boolean operands are sometimes also with creases.

Sorry for the lack of details, maybe the things above are useful somehow.

Okay, again. I was making a boolean operation with some subdiv. Its very unstable (might look into that as well); when I pressed the overlay button, it crashed blender. So I booted up the autoback file and again, all my edge creases disappeared again. I think its due to the modifiers being layered and heavy boolean operations? Though I cannot explain why the crease info isnt backed up, or is just inconsistently backed up

Thanks for the information.

Could be same as #100620 (Random crashes with NVidia + GPU Subdivision (sometimes when activating X-Ray or Wireframe overlay))
Can you share crash logs?:

Please open Blender's installation directory and double click on the blender_debug_gpu.cmd. This will start Blender in debug mode and create log files. Try to reproduce the
error again. Once it crashes or you close Blender manually the Windows Explorer should open and show you up to two files, a debug log and the system information. Add them
to your bug report by clicking on the upload button as shown in the screenshot below or via drag and drop. Please also upload the crash log located in C:\Users\[your username]\AppData\Local\Temp\[project name].crash.txt (or simply type %TEMP% into the path bar of the Windows Explorer).

re edge crease issue:
Since this is inconsistent, I guess auto-save has happened prior to edge crease drawing and that's why auto-save file did not capture creases.

re edge crease issue: Did you ever save that file with edge creases? Or did you apply them recently? How much is the auto-save timer value?

Could you also answer this?

Maybe there's a chance the edge crease issue is related to #95966 and D15927. The internal format and the saved format for edge creases are different. I guess it's possible that could affect things. Maybe that helps for investigation.

Thank goodness This is brought up. I have very similar issue on this.

Obvious Random crash when activating X-Ray or switching to wireframe mode during the edit mode of Material preview . (Yes with GPU subdivision on+ Nvidia 1650 GPU )
and my auto save file edge crease are lost comparing with my old work file.
My edge crease are applied already and saved in old work file. (No edge crease job done during the crashing process )
My auto save time is set to 2 min

This should be fixed with 6d12d43a05. @nick-14, could you test the latest daily builds? Thanks. Sorry about your lost data.
