Flow isnt triggering for catalog item

Debugging that I did:

1. Checked the run as is set to system user
2. Checked if all the flows and subflows were active
3. Catalog item active and in catalog is visible on the portal.
4. No logs generated for flow. No errors
5. In the flow designer  executions ,nothing is coming up. However if I run manual steps and give the RITM raised , the flow runs.

Issue is that flows are getting queued as the flow isn't processing. There is 9 Flow Engine Event Handler. All other are in red Ready. But all Flows are queued, not a single one gets processed. Should I raise a HI case ? or is there any way to solve this .
