Existing test suite failed to open with unexpected error pop up

No matter refresh or reopen Katalon, the test suite failed to open.
But the test suite data exists without damage.
Anyone have same issue? Can katalon team take a look?
katalon version: 6.3.3

Hi Katalon Team,
Can anyone help me out? All used test suite name can’t be used even after old one deleted.
It is really tricky.
