Blender hangs for multiple minutes when opening blend file from networked drive #116675

System Information
Operating system: Windows 11
Graphics card: EVGA RTX 3090

Blender Version
Broken: 3.6, 4.0.1, 4.0.2
Worked: N/A

Short description of error
Whenever a .blend file is opened from a networked drive (over a VPN or on the network), it hangs (grey screen with "not responding") for multiple minutes until the file loads (this also applies to file browser).

To add some context, I copied all of my files and assets from an external SSD to a NAS drive that is now networked. What I believe is happening is Blender is trying to reference my external SSD, even though all needed files are present in the NAS drive, since it is a carbon copy.

I purged my startup file, then made a new file, and saved it to the NAS. No issue. However, when I append in an asset from the NAS drive into that same file, the problem is back. There is nothing missing from the asset itself (mesh, textures, etc.), but it still makes the file take 3-5 minutes to start up.

Additionally, when the external SSD is plugged into the machine, the file loads up quickly.

Exact steps for others to reproduce the error
Open any .blend file from a networked drive

Hi, thanks for the report. This is possibly related to #112599 / #115935 . Can you check?
Did I understand correctly that long startup time is observed when asset library paths are referenced in preferences?

This does appear to be in the same vein of #115935, however, the blend file is being loaded from a networked drive.

I do believe it is trying to reference an unreachable drive (the external ssd that I coped all of my files off of). Though even when I remove all reference to that drive in asset library paths in preferences, the issue still occurs. I also removed all bookmarks and quick access items that may have been pointing to the old drive, but the issue still occurs in existing files.

Thanks. Can you launch blender from blender_factory_startup.cmd batch file then see whether it still occurs?

but the issue still occurs in existing files.

Does it mean issue is occurring in specific files and not observable when default startup file is opened from blender.exe/blender-launcher.exe?
Also, is blender installed locally or in network drive?

Maybe we can launch a package so you will be able to test #116692

Launching blender from the blender_factory_startup.cmd batch file does not have an issue with initial load times, however I still have issues with load times in the file explorer.

It appears after I deleted references to the unreachable drive, the problem (of long startup times) no longer occurs in the default startup files.

By "existing file", I mean any .blend file that was created before I migrated my data from the external SSD to the NAS networked drive. In addition to this, if I append any asset from an "existing file" to a new file that does not have the issue, it will make the issue present when saved.

Also, is blender installed locally or in network drive?

No, Blender is installed on a local drive in my system.

Thanks, it's clear now. Have you checked whether "existing file" has missing linked library/asset references.
Can you share "existing file"? If you make copy of "existing file" on SSD, it loads in less time, right?

@mano-wii may able to investigate it since he is involved in similar reports already

I just want to possibly confirm this bug.
I network through my router a folder that I keep on the desktop of both my PC and my Mac to make file transfers quick and seamless.
I just started using this for Blender files and noticed that anytime I tried to view the Desktop, where I keep the networked folder, through Blender's File Browser that it would hang Blender. I thought this was a soft crash happening so I would just force quit Blender.

Looks like there is a fix going out. I hope it trickles down to 3.6

I can share "existing file" though it is a bit large (1gb). It is a stark example of the issue, though, because when opening from the networked drive it takes ~8minutes 6seconds. On a local ssd, however, it only takes 7ish seconds.

Have you checked whether "existing file" has missing linked library/asset references.

I went through the file, and it should not have any references to missing library/assets.

Ok, is it possible to narrow down the file so we can use it locally to investigate?
Also 81017772f5 is merged now, so please check if this is still an issue in 4.1: https://builder.blender.org/download/daily/

@BB12, since 81017772f5 was committed, can you check if this issue was fixed in latest daily build?

I just tested with 4.1 and no longer have the issue of Blender freezing when viewing the shared networked folder with Blender's File Browser.

Thanks!

@mano-wii
I want to add that I'm not the original author of this bug report though so you may not want to close it if it is still n issue for them.

Hello, apologies for the delayed response!

I believe this does indeed fix the described problem. It is still a bit slow on my end, but I believe that is due to networking issues that are separate from Blender.

I'm glad a fix was reached!
