Issue with LastPass

I have a problem with LastPass (free version). It is used for backup LastPass Authenticator, whereas the last one is used for authentication in our corporate LogMeIn Central.

Some time ago I found out that somehow MFA switched on and I cannot login into LastPass. I don't remember if I have my phone number saved in the profile or just text messages for MFA don't come to me.

Nevertheless I want to disable MFA. But I cannot. I tried to use "Disabling MFA" - entered login and password and was sent with email:

The email contained a link:

And if I go by this link I got en error!!!!

So, what can I do to disable MFA and finally login to my LastPass account??!!

Can anybody help me?
