ouch! vm io bottlenecks mostly... smaller rootfs size (or faster disks) will help you most...
try this on for size...
sed -i 's/CONFIG_TARGET_ROOTFS_SQUASHFS=y//g' ./.config
mkdir -p packages
cp -a ./dl/*.ipk ./packages/
no-sudo
note: you shouldn't be using sudo here...
build@d07b9eb1cf0d:~/openwrt$ sudo make clean
rm -rf /home/build/openwrt/tmp /home/build/openwrt/dl /home/build/openwrt/build_dir/target-x86_64_musl/root-x86 /home/build/openwrt/bin/targets/x86/64
build@d07b9eb1cf0d:~/openwrt$ time sudo make image ...
next time you unpack a fresh image builder don't use it... ( but your current ib will likely be broken if you don't )
i think your disk is failing or you hypervisor is panicking because this aint right...

your typical 200MB/s+ is massively constrained here...
this is the end stage from my community build with 300+ packages added no-squashfs and pre-downloaded ipks copied to packages, 1GB rootfs;
