Conversion failed - GLB to USDZ

Hi! We've been using Reality Converter to convert .glb files (exported from Cinema 4d) into .usdz to work in several AR viewers. But suddenly there's a batch of files that shows "Error code: conversion failed, 1 error" when trying to open a .glb file in Reality Converter. When pressing more info it simply says "used conversion failure, see error code for more info" But unfortunately there is no more info and I have yet to find any solution.

The .glb files have the same settings as all our other files and we've tried exporting them multiple times under different names and, funny enough we got ONE to work on Tuesday. But the same file didn't work when we tried it again on Wednesday so now.. we're stumped.

Anybody have any suggestions for us we might try? If you need any additional info give me a shout or write an email directly to: qa @fibblar.com

Thank you so much for any help!
