U3219Q, MacBook Air M1, display issues

Yeah, MacBook Air M1 same thing. It started like second days since I got the monitor - https://drive.google.com/file/d/1n9edXAXIY1n_5wHbRcQi6_plE6jUKTw1/view?usp=sharing.

Today I got rid of it by pulling the plug and now it's back again.

PS: This problem remains even after I pulled out the USC and power cord. Now I can't get rid of it and in like 10s there is repeating flashes in TOP part of the screen - https://share.icloud.com/photos/09WNSknBThIYgNaxV1MLyNKGg.
