Green cursor turned to red cursor wtf need help

So when after i /all chat and team chat, i cant click on the abilities and the champion would aa by itself. I had to reconnect to 'disable' the glitch. After a few minutes later, when i chatted, the glitch came back and i had to reconnect again. Its so frustrating when youre playing ranked, team mates would be thinking i am bad or trolling. Pls help. This glitch happened after the latest update.
