Thank you @Elly_Tran !, I already had tried suggested solution and working after restart Katalon.
There is no blocker but this issue should be resolved.
As a paid user, not expecting like this issue.

Yeah, sorry for this inconvenience. My team will fix it in the future but please understand that it will not have high priority as it is simple and has easy workaround. Please understand for us. Thank you for your concern

Same here.
Katalon got totally buggy and much worse with the new 9.x.x releases
It happens many times that my Katalon Studio Preferences are gone / resetted and I get the same Java-Error like @atul.rai mentioned almost everytime I start Katalon.
Working with katalon is just annoying meanwhile and I will ask my Project Lead these days if we may can switch to cypress.
We are actually paying for this product and I could open a support ticket but I have no time for reporting all these bugs…
