Error with Save & Deploy in Studio - Accounts - Layputs - Filter - Advanced Filter

Ever since upgrading to 7.8.2 I haven’t been able to perform an Advanced Filter when looking up accounts. I get the following error when I Save & Deploy:
$dictionary[‘YOUR_CUSTOM_MODULE’][‘unified_search’] = true;
$dictionary[‘YOUR_CUSTOM_MODULE’][‘unified_search_default_enabled’] = true;
$dictionary[‘YOUR_CUSTOM_MODULE’][‘fields’][‘NAME_OF_FIELD_TO_SEARCH’][‘unified_search’] = true;

When I perform a Quick Repair & Rebuild, I also gets 2 errors as shown in the attached snapshot.

Can anyone suggest where to look / how to fix this error? I also tried a Quick Repair & Rebuild and get the error

Many thanks for your help.

Even when accessing Studio - Accounts - Fields, I also get error: an error has occurred - $dictionary[‘YOUR_CUSTOM_MODULE’][‘unified_search’] = true;
etc etc
