Cant open or play Valorant

i've been having this problem from yesterday , i had played valorant the day before yesterday it was all right but since yesterday it just wont open if i click or even if i run as admin even the riot client would not start it would flash as if its loading then if i scroll down the only thing that load is the ad for mobile version of riot and soon after that it would close saying that something unusual happened. now its the second day and it does open but wont log me in even if i give them my username and pass . i have tried logging into the website then into riot but still it wont work , also if i try to launch valorant from the saved file it says "windows cannot access the specified device path , you may not have appropriate permissions" pls help and thnk u :)
