Katalon Studio building test is slow

My Katalon Studio is really slow at starting the test. The test itself goes fast, but starting it is really slow.
Katalon often goes “not responding” for a minute before building the application. Also, after a few hours writing tests, the IDE is getting messy and I need to restart it. I tried making a new project and it’s still very slow.

Anyone experienced this problem before or is there any cache we can clear for Katalon Studio without affecting current projects ?

this is still happening. This morning I’ve got to crash the application 2 times, 1 system restart, and after 1 hour I’m still stuck waiting for Katalon to finish starting process. It’s so annoying. It seems there is no solution for this issue.
