Hi Harshraj,
This is a common issue that was seen in the earlier Mendix 11 releases.
I would recommend updating to Mendix Studio Pro 11.12.1 (or the latest 11.12.x patch). This issue has been fixed there, and in my experience 11.12.1 has been one of the more stable versions for working.
After upgrading, the issue should be resolved without needing to recreate your microflow.
Kindly mark this as the accepted answer if it helps.
