i cant buy valorant points with Paypal (EUW)

I am logging in to my paypal on valorant, and then right after, It kind of loads up with a "securtity challenge" box by "captcha" that I have to click on, but nothing works. (i am not able to click on it, nothing happens)

btw: when i am clicking the VP shop, it starts lagging. Also when im trying to log in to my Paypal it starts lagging whatsoever.

please help me with my problem, thank you..
