USB-C 90W signal issue with Dell U2722DE

My MacBook Pro M1 2020 that I had connected to my new Dell U2722DE via USB-C 90W port (power and video) worked for a few days. Randomly it has now stopped working via that port and goes into standby after not finding the source ("No USB signal from device"). I found that solution could be updating MacOS firmware for this monitor found from Dell site. I wonder if there is only firmware for Windows system installed when out of factory? I try to install the Mac firmware to it via both HDMI and DP cable but it demands USB cable, any ideas how to solve the install problem because can not use USB-C 90w port?
