I'm about to go crazy. This issue is still unresolved.

This is log file. I need to solve this problem without creating a new database. We moved our server to a different company. It was working smoothly before moving. We encountered this problem after moving. I have tried many ways for a solution, but I am not successful. I am saying there is a problem during the move, but the new server does not accept it. It claims to be happening smoothly. Please help me. I need to solve this problem without deleting this database. Because I don't want all the information and products I enter deleted.

There were indeed some issue while moving. The log clearly says

Invalid object name 'ScheduleTask'.

which means that the table ScheduleTask wasn't found. There may be other tables as well.

I would suggest you to make sure that database was transferred correctly.  You can use the schema compare tool to compare the old and new database schema.
That way you might succeed without creating an entirely new database. Note that it totally depends on where the migration script failed and how much data failed to transfer from old db to new.

Anshul
