Having the same problem here! And it's 2025 now! very disappointed...

how did you do this? "I tried replacing !/usr/local/bin/python3.7 with !/usr/bin/env python3 in all python scripts"

btw, I am trying to run usdzconvert in rosetta terminal. I started having this problem since I upgraded the macOS to 12.3 and installed usdz tool version 0.65. Prior to that, I was able to run usdz tools within rosetta terminal.

Have you solved this problem? space_moon's method does not seem to work.
