Run all frappe and erpnext commands from
cd /home/satish/Workspace/tru/frappe-bench

this also i will try but not getting results

What does
bench --version
report?

sry i can’t understand what you say

enter
bench --version
in
cd /home/satish/Workspace/tru/frappe-bench

4.1.0

sorry and this
bench list-apps

frappe
Erpnext

OK if you were installing site1.local when this issue occurred:
bench drop-site site1.local
bench update --reset
bench new-site site1.local
bench --site site1.local install-app erpnext
bench start

done i have delete the first app and reinstall the new app.
