I cannot get paid via PayPal

I have been using PayPal for over a year, and this time I only have the
Fiverr Revenue Card button available to withdraw my money. I cannot click
PayPal Account button, I am not allowed. It says some changes occurred in
my PayPal account, however, I never changed anything on it. I cannot
understand what happened.
My old MasterCard have expired in April. I use another MasterCard now. Does
it have to do something with this issue?
I have already contacted PayPal. They said nothing changed in my account
and I should contact Fiverr, because Fiverr must have something wrong.
This is the PayPal team's letter:
''Thank you for contacting PayPal.

I have reviewed your account and I can confirm that your account
is in good standing and there is no reason why you should not be able to
receive payments.

I can also confirm that your account is verified by the card ending xxxx
Please ensure that the merchant is sending the payment to your correct
emails address.

I would also encourage you to ask the merchant to contact us directly as
there may be an issue with their account.

It is my pleasure to assist you and I hope this resolves your issue

Please do not hesitate to contact you if you require any further assistance."
Thank you in advance!
