Prebuilt binaries in librdkafka.redist are linked with RHEL compatible distributions. We have upgraded to RHEL 8 and compatible version and they have this bumped soname that is different from Debian/Ubuntu one.

A solution that works is to remove usage of librdkafka.redist, this way, and install librdkafka Debian packages from Confluent Debian clients repository.

<PackageReference Include="Confluent.Kafka" Version="2.5.0" />
<PackageReference Include="librdkafka.redist" Version="2.5.0" ExcludeAssets="All" />

That is necessary only if you need to use GSSAPI/Kerberos.
Given this difference we can think about including in librdkafka.redist a librdkafka shared library built in a Debian based system, that is currently not available. But at the moment preferred way is through librdkafka Debian packages if you need GSSAPI authentication, or to switch to a RHEL compatible distro.
