Two things to maybe try
I copy a 64MB image I copy to an USB flash, so the GPT doesn't
match size of so use this to fix that issue.
echo fix GPT layout by running parted -l
echo -e "Fix" | parted -l ---pretend-input-tty
Could also just run parted on it manually.
Could also be a bad USB flash.

-e, --end-at=NUM Last NUM.h2w file to be read
-p, --show-progress=NUM Show progress if NUM is not zero
-r, --max-read-rate=KB/s Maximum read rate
-s, --start-at=NUM First NUM.h2w file to be read
-?, --help Give this help list
--usage Give a short usage message
-V, --version Print program version
Mandatory or optional arguments to long options are also
