Hello,
Basically this happens that for some reason when the database is not upgraded during the migration from a previous version .
In that case go to
\Program Files\Symantec\Symantec Endpoint Protection Manager\bin (substitute Program Files (x86) in this path if working on a 64 bit system ) and run upgrade.bat then repair the SEP manager installation through Control Panel - Add / Remove programs
Check this Article:
Query Failed returned on Home page in SEPM console after a successful migration from 11.0.6 to SEP 12.1

Secondly, you can also try the below steps (incase you are using a SQL Database):
- Login to SQL Server Management Studio
- Expand the Server
- Expand Databases
- Expand sem5
- Expand Security
- Expand Users
- Right click sem5 and choose properties
- Select db_owner
- Restart Symantec Endpoint Protection Manager Service
- Login to console successfully and view all tabs.
Hope this works for you!!
