The follow is a partial simulation of what you have
done. It uses the armv7 snapshot world via chroot on
an aarch64 machine that can execute armv7 code, using
a mount of armv7 kernel+world snapshot based media.
(I abbreviate command line prompts.)

# mount /dev/da1s2a /mnt

# chroot /mnt

# uname -apKU
FreeBSD generic 14.0-ALPHA1 FreeBSD 14.0-ALPHA1 aarch64 1400094 #0 main-n264678-136fc495615f: Fri Aug 11 12:22:32 UTC 2023     root@releng1.nyi.freebsd.org:/usr/obj/usr/src/arm64.aarch64/sys/GENERIC arm armv7 1400094 1400094

(Note both the "aarch64" and the "arm armv7" from the chroot
context.)

# pkg install git
. . .

# git clone -o freebsd https://git.FreeBSD.org/src.git /usr/src
Cloning into '/usr/src'...

So this really used the aarch64 kernel and its FreeBSD 32 compat
support but was a armv7 world. The combination worked just fine.

It may be that the problem you had was not local to your machine,
or even to your local network. Some received byte(s) might well
have been bad.

It will be some time before I put back the armv7 media into a
armv7 system and boot it: I'm doing other experiments.
