MLMarkerTracking Doesn't Start Scanning in Unity Build

Unity Development

I'm using the MLMarkerTracker API on a QR code, and when running it from the App Sim Target it successfully detects it as well as its pose. After making a build though, it no longer detects the QR code.

Unity Editor version: 2022.2.1f1
MLSDK version: 1.3.0
Host OS: Windows 11

Error messages from logs (syntax-highlighting is supported via Markdown):
Using Android Logcat this is what I get in the console right after I call the StartScanningAsync function:

Then at the very bottom, it says "Error: MLMarkerTrackerUpdateSettings in the Magic Leap API failed. Reason: MLResult_InvalidParam".

What version of the Magic Leap OS is running on your device?

According to the Magic Leap Hub I'm using:

Version 1.0.0
Build B3E.220818.12-R.046-R.420
Android API Level 29

Try updating your device to the latest release B3E.221128.08-R.092 listed as 1.1.0 in the Magic Leap Hub

That worked, thank you!
