change email failed

I'm trying to change the email on my account and receiving the message "Your account email cannot be changed at the moment. Contact support for assistance."
i don't know how to resolve it .

 

Hello, could you provide us with your Parallels Account email address via the private message?

 

my email address is 「pjwx4***gu@privaterelay.appleid.com」. i want to change it to 「47**66376@qq.com」

 

Hi, unfortunately we didn't find Parallels Account associated with 47**66376@qq.com
Could you create a Parallels Account and let us know once done, then we will be able to move your license to 47**66376@qq.com
