this mac is linked to a different Apple ID but shows my email under dots

I erased my macbook pro 13 2020 4 TB3. It shows Activation Lock window on start up.

It says that this mac is connected with an Apple ID. Asks to log in previos Apple ID that was used with this mac and shows part of email with dots. I know this email. It's my Apple ID and shown letters matched.

I start to log in and receive red error message "this mac is linked to a different Apple ID".

I checked many times this mac is absent in list of devices on iCloud Found My and Apple ID trusted devices on https://appleid.apple.com/

Unfortunetly I don't remember mac user's password and now it says that I tried to many times with incorrect one.

I tried to reset Apple ID password. But nothing helps

How it could be different if there was only my Apple ID ?

How to restore it now or find out which Apple ID it could be if there was only mine?
