Don't know how to check out such a PR, but I downloaded the SDK from ZWO and installed (only) armv8/libASICamera2.so.1.26 on my Pi4.
Indeed I can again connect to my two cameras (290MMmini and 183MC), take images etc.

With the release of the updated libASICamera2 from ZWO, I'm going to mark this topic as solved.
Thank you all!
