Hello,
Each user has a default database. When you connect to computer that is running Microsoft SQL Server, and you do not specify a login database, the default database is used. To avoid the error try this app -https://www.sqlserverrepairtoolbox.com/

It repairs data types, views, procedures, tables, keys, indexes and other objects
