This appears to be because the app assumes it's on C:
If it's not (and it can not-be, because Microsoft allows you to change the default App drive via Settings), a lot of things will break.

Nope. Uninstalled, reconfigured app storage back to C:, reinstalled, same issue persists.
Also, no VRCFaceTracking folder in AppData.
No idea what's going on.

[orcinus]

Okay, figured it out.
App expects the Windows Temp folder to be on the same drive (volume) as itself.

Since it uses move instead of copy (and delete), which only works within the same volume, moving the module from temp where it was downloaded, to where it needs to be, fails if Temp is elsewhere.

I have same error. How can I fix it?

This is the issue I been getting except I can wipe the folders within app data and the built-in modules load.

A second issue is that no matter what I do, the 3rd party modules (like eyetrackvr or pimax) will never load, not even if I install them manually as a zip, modules are added to the app data folder, but these fail to load completely.

To the devs, I did a more specific rundown on my thread on discord: https://discord.com/channels/849300336128032789/1189778058610233404

I should mention I am on windows 11 23h2, so please check if you are able to recreate this issue on the most recent w11 version.
So far, un installing, reinstalling, wiping data etc has not worked. Not even adding the modules directly on CustomLibs, it's become clear that only the modules located on StockLibs are the only ones that load correctly on the app
