The screen flickers right after login

A few days ago I’ve installed Manjaro KDE plasma edition, since then I’ve been facing a wired screen flickering right after I log into desktop, the same happens when I log out and log in. Rest working fine no flickering when I work on PC after login.

AMD Ryzen 2400G
8 GB ram
Manjaro installed on SSD

Someone, please help! :pensive:
