dbt version 1.6.9 / 1.7.1 parsing error

error while running dbt.

Running with dbt=1.6.9
Registered adapter: snowflake=1.6.5
Unable to do partial parsing because saved manifest not found. Starting full parse.
Encountered an error:
Compilation Error
Model ‘model.assessments_api.int_assessment_group_lookups’ (models\intermediate\assessment_groups\int_assessment_group_lookups.sql) depends on a source named ‘ASSESSMENTS_API.DBO_ASSESSMENT_GROUPS_CURRENT’ which was not found

was working fine before. couldn’t run any more. no changes have been made to the solution.

tried below commands to clean and build

dbt clean
dbt deps
dbt run

tried with dbt=1.7.1 and 1.6.9 versions still facing same issue.
