Hello Saleh Saad,
Thank you for reaching out to Microsoft Q&A forum
Since you have already changed your password, I recommend the next step is to contact Microsoft Support live chat for further assistance about the issue.
- Open a website link - Contact - Microsoft Support
- In the box below "We're here to help", type Microsoft 365, click "Get Help", and then click "Contact Support" below.
- In this section, you will need to sign in to your Microsoft account.
- Select "Microsoft 365 and Office" under Products & Services, select "Technical Support" as the category, and click to confirm
- You can select " Chat with a support agent in your web browser " to access the chat window.
