Hi Reemali,
Please try connecting the debugger to the flows, if any are configured on the default home page. If not, check whether there are any role-based home page flows and add the breakpoint to debug if there to identify the root cause, provided the issue is reproducible.
Additionally, try changing the log level to Trace or Debug for deeper analysis of the issue. Also, please inspect the application from the browser and check the Console tab to see if there are any client-side errors.
Further, I would recommend adding an error handler in the flows wherever there is a possibility of the issue recurring, so that similar scenarios can be handled more effectively in the future.

Sathish Kumar
