Can't load on android 9 device.

I put my .glb files on http server, and download on android's Application.persistentPath. the file can download and store successfully, but when l use GLTFComponent.load to load the glb file, but it doesn't show anything. I have testted it successfully in unity editor.
I also switch to other plugins, GLTFUtility and glFast, it occur the same proplem. So, if any one can help me, I'll be very appreciae.

Start by reproducing GLTFComponent.load on an Android 9 device with a downloaded .glb in Application.persistentPath, then compare it with the successful Unity Editor case. Check whether the asset loads and displays on the device; the issue is done when the downloaded model renders successfully on Android 9.
