External monitor stopped working after update to Sequoia 15.1 on AirM2 2022

Hi. After update to newest system from 14.x my external monitors stopped to work with my air... I have some cheap projector that I connect to using HDM-USB-c cable, but also I got Dell 2k monitor that both worked fine until update... So now when I plug in monitor or projector it works for couple of seconds ( 3-4 ) and then it just shows 'No Signal' message. I cannot find any solution online to this issue, I tried cloning, reseting settings, manually setting various settings... nothing helped. Does someone found solution to this stupid issue that im not sure even apple is aware of... Or maybe downgrade to older system version would help?
