What is the purpose of the change

Background/Problem:
When SR (Script Resource) tasks are retried, the init_sql loading process encounters exceptions. The current implementation does not properly handle the retry scenario, causing SQL initialization to fail during task retries.

Purpose of Change:
To address this problem, this PR fixes the init_sql loading logic to properly handle task retry scenarios, ensuring that SQL initialization works correctly during both initial execution and retries.

Value/Impact:
After the change, SR tasks can be retried without encountering init_sql loading exceptions, improving system reliability and task execution success rates.
