P2719H, DDPM 2.0.0.72, not detected

I have Dell P2719H connected by DP to PC, but DDPM 2.0.0.72 doesnt detect monitor.

I have enabled DDC/CI in monitor settings, old version of Dell Display Manager works fine.

Where is problem? Dell tells on product page that my P2719H is supported by DDPM 2.0.0.72 and download this application is offered officialy.

I don´t understand, really I must buy next time other brand of monitor and reccomend this for all friends around me? Really? Sorry for this, but I am angry when something works and someone must change it to unusable thing...

Thanks for help anyway. (OS is Win 11 24H2 x64)

PS: Is only one solution to use old DDM 2.3.2.23 ? I tried uninstall DDPM 20072 - restart - install DDM23223 - restart - install DPEM177 - restart - install DDPM20072 - restart - and result is nothing - monitor not detected.
