I have found the solution, wait 24 hours before you try to send payment, after 24 hours you should be able to send again. Paypal applies soft locks to accounts if they detect unusual activity, like if you usw VPN for example or someone else acess your account. Try changing password and don't login for exactly 24 hours, if you try to send payment before 24 hour passed it will reset timer and you will have to wait more (don't do this trust me from my own experience)
