Hi,
Sorry to hear you had issues with the upgrade.
The problem you describe appears to be related to the release notes item
[5.3.2] (5.3.2.1 actually, but I cannot find the direct link to that).
The exact case with /var/lib/dpkg/status is not mentioned, but it could
be that there are some permissions on your system that forbit "_apt" to
access /var/lib/dpkg/status.
* Could you please try to login in as the _apt user and check that it
can read /var/lib/dpkg/status?
- If it fails, please attempt to figure out where the permission
fails (e.g. [dir-test])
* If you have any policy framework enabled (SELinux or AppArmor),
please check if any of these are forbidding the access.
Thanks,
~Niels

[dir-test]: Example:
ls -ld / /var /var/lib /var/lib/dpkg /var/lib/dpkg/status
