white screen buffering stuck while paying for valorant points

Everytime I'm going to do a transaction for VP in valorant, after giving credentials, the screen becomes white, then buffers and then gets stuck.

No the game doesn't crash or anything, the white screen pops up and buffers then stops buffering and the transaction isn't successful anymore.. have been trying to buy vp over a month now and this problem keeps occuring.

Please help me with this
