My macbook pro which is linked to my appleid and find my account is locked by activation lock.

Hello there, i purchased a macbook pro 2020 before 2 years, on year 2021. I purchased it from a local electronics dealer in the region where there is no apple support. At that time I attached my appleid to the device and i also activated find my for the device. I can still see the device on my appleid device list and also i can see it in find my devices list.

The problem is before a week i found an update notification in the setting and i go for it. Immediately it shows activation lock.

I tried to activate and login using my device password but it shows password error and password unacceptable due to multiple error message. I am sure the password is correct.

Then I tried to use appleid and the big problem showed up. It shows b*****@yahoo.fr which is totally new for me. I imagine it is previous owners email id. I don't know the original owner and the local dealer also can't trace him/her. Even I can't see the full email address to communicate.

I tried to fill apple support how ever it requires proof of ownership which shows only purchase only from supported region. I have a receipt for my purchase from my local electronics dealer but it is not helping.

My questions is

1. Can a device linked to multiple appleid and find my account at the same time?

2. Considering my condition what is the solution?

Thank you in advance.
