Tomorrow I was proposed for a Meta XR Simulator (v78) update on Unity 2022.3.62f (Win11) but I get this error:

[Meta XR Simulator Installer] Central Directory corrupt.
UnityEngine.Debug:LogError (object)
Meta.XR.Simulator.Editor.LogUtils:ReportError (string,string) (at ./Library/PackageCache/com.meta.xr.simulator@78.0.0/Editor/Utils/LogUtils.cs:40)

Any suggestion?

    Small update: the same happens on Unity 6.2.

      Same here. I tried removing it through the Package Manager and reinstalling it, but it keeps reverting to the same old version. I suspect this is because it's a dependency of the Meta XR All-in-One SDK. We might need to reinstall the SDK itself to force an update. I also checked its installation folder, and it only contains two older versions (you can find its directory in Preferences under the Meta XR Simulator tab). I can’t reinstall the Meta SDK right now because I’m in the middle of a project and don’t want to risk breaking anything. I’ll update you once I give that a try!

        I use Meta XR single packages in my project and I was able to remove and reinstall  the XRSim package. Unfortunately this did not work.
        I suppose the bug happens only in "older" projects that had a long history of Meta XR sdk updates.

          I tried removing the Meta SDK from the PM and reinstalling it (including XRSim), but the simulator issue persists. I think we need to clean the root project folder of any cached data related to the Meta SDK!
