Instagram error message when logging in?

My Instagram has not worked for several weeks / months, I have already written to the support but they have sent me only any links that bring nothing and ignore me now. The error message is "Error. Sorry, there's a problem with your request." as soon as I sign up. My friend with the same mobile phone (Huawei mate20 lite) can't log in anymore. And I do not think that jz has anything to do with Huawei ban.
I'm happy about all the answers

No, that has nothing to do with the Huawei spell. I have a Huawei myself and Instagram works fine. Maybe your account has been suspended or shut down. Have you ever tried to enter PC? Maybe it's there

I can easily log in to the site. Only the app does not work.
