Stabilize version of ERPNext

Hi, I want to stabilize the version of ERPNext and wants to do development in that stabilized version only. Can anyone help me out for the same. Any leads would be much appreciated.

If you clone the branch version-14 then you have a very stable version of ERPNext.

Here is a sample command you can issue

bench get-app erpnext --init-bench --resolve-deps --branch version-14


Already tried with this but still not working as expected. now getting an error that after migration, a blank page is displaying on the frontend side
