It might be a temporary issue with something in github. debian 10 is EOL.
I only found 1 search result for the same issue.

The issue seems to be that Debian moved these repos to free up space on the main mirrors.

https://lists.debian.org/debian-devel-announce/2024/03/msg00003.html

It would be possible to point to the archive mirrors to enable testing on this platform, either by running these extra commands on that platform, or by preparing a Debian Buster image with the change already made:

sed -i 's|http://deb.debian.org/debian|http://archive.debian.org/debian|g' /etc/apt/sources.list
sed -i 's|http://deb.debian.org/debian-security|http://archive.debian.org/debian-security|g' /etc/apt/sources.list

My unsolicited opinion: drop Buster or pay for Extended LTS from Freexian.
