InstantView issue, macOS 26, M3 MacBook Air

After installing macOS 26 my instant view no longer works, but I can see a single monitor in clamshell mode. I am using dual LG basic 32 inch monitors. The system is worked fine for the last month and my only change is upgrading to macOS 26.


Thank you very much.

MacBook Air 15″, macOS 26.0
