Running Roon in on macOS with Open ZFS is not an officially supported environment. It is considered Tinkering. Roon does not stop users from using their software in unsupported environments which is great for the tinkerers among us; however, when you do so, you are also taking on the ongoing support for that environment.
This is why your post was moved, back in 2021 by Roon staff, to the Tinkering section so other users who may also be using your environment can help you with diagnosing and resolving your issue.
If this does not work for you, then I would recommend running Roon in an officially supported environment for the stability and support you are looking for.
