Hi Roee,
I believe this initial issue to disable DNI might be related to https://community.intel.com/t5/Intel-Quartus-Prime-Software/Bug-Import-of-QDB-file-partition-fails-in-Quartus-Pro-versions/m-p/1554546#M80987
Regarding the disable of DNI, you are not encouraged to disable it. We want customers to run in DNI mode as much as possible. As mentioned in above issue. Yes this is a bug in DNI and I have provided some workaround and meantime waiting for patch release for affected version. Yes there is plan submitted for permanent fix in 24.1 as for now. I will put this to close pending as this is clear bug. We can remain communication in another case.
