U3219Q, MacBook Pro, USB Type-C not working, #2

I have the exact same problem with macbook pro 16 and U3219Q. USB-C display worked fine for about 2 months and yesterday suddenly the display signal is gone on USB-C port - only charging and USB hub is working.

I suspect this is an issue with mac usb-c connection. I have another U3219C connected to a lenovo laptop through USB-C for months with no issues.

At this point I'm hesitant on even claiming a warranty as the replacement might display the same problem eventually.
