Studio fails to load the majority of MeshParts and textures

[BlackSp_oon (Jonathan)]

Summary

In Studio edit mode and play mode, most textures and MeshParts fail to load. Rarely, the same issue occurs in Roblox Player as well.
The following error log sometimes appears:

MeshContentProvider failed to process https://assetdelivery.roblox.com/v1/asset?id=18718319163 because 'could not fetch'

Where it occurs

It occurs on Studio for all development members of my group.

When it started

From November 12, 2025

Reproduction Steps

1. Open any of our group’s places in Studio
2. Wait for the place to fully load in edit mode
3. Observe that most MeshParts display as grey boxes or missing textures
4. Check Output window - “could not fetch” errors may appear
5. Press F5 to test in play mode
6. Observe that the issue persists
7. Close and reopen Studio
8. Notice that different assets now fail to load

Details

• When reopening Studio, the textures and MeshParts that fail to load change.
• After clearing Studio cache (%LOCALAPPDATA%\Roblox and %TEMP%\Roblox) and restarting the PC after reinstalling Studio, the issue sometimes improves, but the issue reoccurs when reopening Studio.
• When running with Studio’s multi-client simulation (Server and Client), this issue is less likely to occur. However, the issue still occurs in Studio edit mode.
• This issue rarely occurs when running in Roblox Player as well.
• Even if assets that failed to load are reloaded with ContentProvider.PreloadAsync(), they never load successfully.

Other things I tried

• Setting Workspace.StreamingEnabled to false
• Changing Studio settings
  • Increasing mesh cache size
  • Setting edit quality level to maximum
• Turning off Firewall and Windows Defender

System Information

• OS: Windows 11 Pro
• GPU: NVIDIA GeForce GTX 1650
• Studio Version: 0.699.0.6990877 (64bit)

This appears to be the same issue as this;

MeshParts not loading in

In my game, meshes will simply not load, this has been going on for a couple of days, however I’ve tried many things such as trying to re-authorize assets and it doesn’t seem to be the issue, however in my own games, I can see meshes I’ve uploaded, but other people in my game cannot. And other meshes that my other developers have uploaded, will not be shown to me sometimes, and it’s not specific meshes, it’s completely random. No errors appear anywhere in the F9 logs that I can go to, however I …

We are waiting for a response from anyone on the Roblox team. It’s a major issue that we pretty much are all facing

Hey @BlackSp_oon
