Hi @abreen
For what you are describing, I suspect that something has probably changed in the Subject of the incoming emails or in the incoming email and that's why the flow is not firing, I would recommend that you check to see if you are filtering the email correctly.
You can also try testing by creating a new flow and using the "when a new email arrived" trigger without any filter to see if the trigger is working properly.
Let me know if that works.
Regards.
