Getting error of Selenium Exception on Katalon 7 when scripts downloaded from older version

Hi today i upgraded Katalon 7 and i am getting the these 2 error.

The project was not built since its build path is incomplete. Cannot find the class file for java.lang.Object. Fix the build path then try building this project

|The type org.openqa.selenium.WebElement cannot be resolved. It is indirectly referenced from required .class files|Functions.groovy|/C%%Users%RAgrawal%git%billing-katalon-7%Billing Workbench.prj/Keywords/myFunctions|line 1|Java Problem|

How to resolve this?

Hi,

Today i upgraded Katalon Studio version to 7 and i would like to evaluate the version 7 release. But without providing licence details, i am not able to use Katalon Studio 7 version. This is tedious .
Earlier i was working on Katalon Studio version 7 which is free version and now i would like to downgrade my Katalon studio version from 7 to 6 version.
Please suggest the same asap.

This has been removed in KS 6. Please remove all references to net.lightbody.bmp in your test scripts. Also try deleting folder bin, Libs, .classpath, .project and open the project again.

I am also facing issue with these 3 errors, not sure how to get rid of these.

java.lang.NoClassDefFoundError: org/openqa/selenium/WebDriverException

Test Suite working fine when running through command line but not when running as a Jenkins Job on same machine?
