Hi Ankit,
Can you please add temporary FPT access as well?
This looks like some sort of a 3rd party plugin or code conflict. The error logging is disabled or routed to a log file, which I can’t see from the front-end.
First I will try to reinstall the plugin to make sure there are no corrupted files or anything. Then enable error reporting and debug through the file tree to see where the error is triggered exactly.
