C3422WE, M2T112 firmware issue

C3422WE have updated to M2T112 just in the last week released. however, after updating, the monitor flicks on and off when coming out of sleep, webcam and mic doesn't work and not detected, microphone button on the front of monitor is always lit up red. no buttons on the front for teams works anymore. i only get the dell speaker option for audio output and when selected, no audio comes out, and the echo-cancelling speaker phone option in audio output and input no longer is detected or is an option. all using usb-c. use to work right before update.
