This is an odd one. I can read some exported files from C4D and some don't. All files were exported the same way, the only thing I can guess is that might have to do with file size. The smaller sub 1Gig files open fine, I have a 4 gig one that won't open. I can open the file just fine in a PC.
I'm on 19.5.640 on OSX 12.2.1 The error is attached in an image.

Have you tried saving it as binary (.usdc) instead of ASCII (.usda)?

I'll try to get those as binary to see if that will solve it. Thanks.
