Custom theme error will be output after data migration from Magento 1.9.3 to Magento 2.2.4

Question

Custom theme error will be output after data migration from Magento 1.9.3 to Magento 2.2.4.

I migrated data from Magento 1.9.3.1 to Magento 2.2.4. No error was output at that time. We were able to migrate the data without problems.

However, after installing and importing the Ultimo theme file and checking the front end, an error was output.

Below is the error contents.

Exception #0 (LogicException): Unable to load theme by specified key: 'ultimo/fascinate'
