Facing skill issues lately

Hello there. So the thing is I am facing skill issues lately. I have agood computer to run valorant and a good network connection. I play good valorant on my level and I also get decent kills on competitive matches. When I wake up and turn on my computer I directly queue to competitive match without any warmup and still I am able to get kills and clutch and this is like regular thing. Now one day I don’t know what happened overnight , I lost a game 3 days ago with very less kills and bottom fragging. That day lost 5 consecutive competitive matches in a row. I was sad but I thought I was having bad day and ignored it. Now I have been losing matches and getting kill is also now difficult for me. If the enemy is not looking at me and I shoot him, the enemy turns and kills me easily even though I had the advantage. Its not like I don’t know game. I have knowledge about enemy’s locations like I know someone is going to be at certain spot and I enter pre firing and enemy is there but still I get killed. Now I am feeling low confidence in every match due to this and sometimes I walk and shoot like a new player . Its like I lost all skills overnight or something. I want to ask the viewers if they faced something like this in their gaming life and if possible suggest some warmups or practices to do to acquire the lost skills. Thank You.
