After updating to Darwin 22.4.0 (Macos Ventura 10.3) on intel, lost most live data and all statistics charts.

Suddenly while running my sole project einstein@home on iMac 2019 GPU, I lost all graphs in the Boinc manager statistics window pane even though the project name is selected and lost most data in projects and tasks in the advanced view setting. 
In tasks, I see the the app and WU names but no progress or time except only when it's complete it shows 100%.
Wu are being processed as before, just no live data. 
In projects window pane I get O credit everywhere. 
I ran maintenance routines and reconstructed boot cache with Onyx, unisntalled the Boinc app completely, rebooted, reinstalled, : no change. ideas ? Thanks. Pierre
