Problem with login KDE Plasma SDDM dual monitor nvidia

I have a problem logging into KDE through SDDM. After entering the password, the password field turns gray, and it freezes without logging in. However, since I have two monitors, I can enter the password on the second one and log in correctly. The computer is a Ryzen 9 with an RTX 3090 Ti using NVIDIA drivers. Everything is up to date.

I getting error:

paź 18 20:46:27 archblack sddm[747]: Auth: sddm-helper exited successfully
paź 18 20:46:27 archblack sddm[747]: Greeter stopped. SDDM::Auth::HELPER_SUCCESS

How to fix this ?

ps.
I have the same issue on a second computer, even though the graphics card is an AMD Radeon 7900 XTX. However, here I cannot log in because the screens are mirrored before login, and only after logging in does the second monitor switch to extended mode for the first screen.
