My ingenuity is disappeared

Hello! The situation is the following, I returned home from work in the evening, sat down to play, ran maps and noticed that some of my skills were not working. It turned out that my character’s belt slot was empty. I checked all the tabs, buyback stores, etc., it’s nowhere to be found. I played in the morning around 4:00 UTC, and now it's 17:20 UTC. 20.12.2024. Upon further investigation, my friend who played all day said that I entered the game at lunchtime, but I was not at home.Supposedly someone has gained access to my account. Help me find out the reason.
