Channel Output issues after upgrading to Tahoe 26.2

I'm running Logic Pro X on my Apple M4, upgraded to Tahoe 26.2. After the recent software upgrade I am having issues with Logic Pro X 11.2.2. The monitoring of any track I create is not sending a signal to the main channel. There is an input signal when I solo it. It will record , again with no monitoring. Creating an aux channel sends signal but only to the left side of the main channel . Switching to microphone input has no effect, toggling buffers no help. Updated all my plug-Ins (Waves) and Interface (UA Volt 2 76) Tried starting in Rosetta mode, no change. Any suggestions?
