No secondary click on anything (contextual menu).
I just upgraded to Tahoe 26.3 and I'm not able to 'right click'/ 2 finger tap to open any contextual menus on any app.
MacBook Pro (M1 Max, 2021)
Have you rebooted your Mac? Does holding the Control key and clicking give the contextual menu, as expected?
Make sure the setting is enabled in System Settings > Trackpad (and the tap to click setting, if you tap).
If they are enabled, disable then reenable them.
As a data point, secondary click is working normally on 26.3 for me, on two different Macs.

Update. Found the answer here.
Basically, just go to settings->trackpad and turn off, then back on, the 'secondary click' selection.
I see you found it as I was typing. Well done!
