You need to call jamf support. You can’t downgrade versions without restoring the database as the different versions make changes to the schema. Do you have a backup of your database from before you did the initial update?

@ iJake yes I have and I tried with that but still it is showing the same now it is only working with 10.10.1 after for any version for example 10.13 & 10.14 it is showing "Jamf Pro Startup Suspended"

@Durgule As @iJake asks, do you have a backup of your MySQL database from before you 1st installed JSS 10.21? You really should restore it along with the version of the JSS you started with, then consult the Installing Java and MySQL for Jamf Pro 10.14.0 or Later document on the Java requirements for different JSS versions. In short, JSS 10.13.0 and earlier require Java 8, while JSS 10.14.0 and later require Java 11.

You also need to look at the Incremental Upgrade Scenarios for Jamf Pro 10.0.0 or Later guide as you cannot upgrade directly from JSS 10.10.x to 10.21

Did you blow away the database before restoring? If not, there will be tables from the 10.21 JSS that didn't exist in the older versions, and those can interfere with startup.

I ran into this issue with a rolled-back upgrade when I tried to upgrade again. The JSS was trying to convert a table during startup, but that table already existed from the prior failed upgrade attempt, and I had to drop it so the upgrade could proceed. The JSS log should have better error messages that can help.
