TestCase opening attempt results in crash

Hello,


i faced this issue yesterday. I appreciate any help, as i am totally blocked by this bug…
katalon.versionNumber=8.0.5
katalon.buildNumber=208
java.version=1.8.0_181

Reproduction Steps

  1. Create new Project
  2. Create new Testcase
  3. Open newly created Testcase

Expectation:
Testcase Is displayed in Katalon Studio

Result
Katalon Freezes after “Operation in Progress” Message opens(but is not fully displayed, some icons are missing) The mesh of the standard testcase view displays, but not the whole frame or any content.

Error LOG: (the last one with show.ext appeared twice, i removed it due to character limitation)
