Basically, I keep getting Error Codes 46 and MeshContentProvider ‘Unknown Version’.
I’m currently on laptop, and the problem is just here, because when I try launching the same project on PC, everything seems to be completly nornal.
I have no idea what’s happening, and so on - I need help.

Most assets fail to load

Reproduction Steps I’m not sure how to reproduce it, because I’m the only one I know experiencing it. It just happens as soon as I load anything in studio or any game. I’ve tried: Different devices: Windows 11 desktop, Windows 10 laptop, iphone Different networks: Wifi, ethernet, mobile data, VPN Reinstalling, wiping caches/registry, restarting machines, different accounts, different games, different files Expected Behavior Game assets to load normally. Even a blank baseplate should still…

This thread and comment might be helpful to your problem.

Okay, we recently finished reverting a service change, and we think it may help with this issue. It appears that while that bad change was live, invalid/“bad” cache entries may have been created in your http and plugin caches on disk. Manually cleaning these directories again (now that the service has been rolled back) may be a workaround for getting you un-stuck:

• AppData\Local\Roblox
• AppData\Local\Temp\Roblox

I had a similar problem where the studio would not launch and did [disk cleanup - (c) - temporary internet files - clean up system files] fixed it.

Okay… I got it. It was pretty close to anwser You send me.
But the differemce is that i have to remove all files from AppData that contain ‘roblox’ in it.
LITERALLY every single one.
I’ve tried removing just :
AppData\Local\Roblox
AppData\Local\Temp\Roblox
But it didn’t worked at all.
Also - I did this after uninstalling Roblox + Studio.
Now everything works fine.

But thanks anyway for trying to help me.

Replying in case other people run into this issue - like ImRealLenny said, delete all the files labeled Roblox in the AppData folder, then reinstall Roblox. This started happening to me today and I tried several times only deleting the AppData\Local\Roblox and AppData\Local\Temp\Roblox folders to no avail. It finally fixed the issue when I searched “Roblox” under AppData in file explorer and deleted all the file results.
