What are the causes for SQL error 3154
There are many reasons for this 3154 error to occur. Some of them are:

What are the methods to fix SQL error 3154
One of the solutions is to restore the backup set to a different SQL database with a different name.
Always, make sure that the file which will be created does not exist already and is not being used by any other database.
We also have other solutions. Some of them are:
Using T-SQL Command
Here, for resolving the error we overwrite the already existing database through RESTORE DATABASE command using WITH REPLACE clause. Here,
RESTORE DATABASE XYZ FROM DISK = 'C:\BackupXYZ.bak' WITH REPLACE
Using SQL Server Management Studio

The steps to follow are:
- Create a database with your desirable name.
- Right click on the Database >> Tasks >> Restore >> Database.

Using a dedicated recovery tool
