This works for me:

Answer from Embarcadero Support:

If you logged a support case about the IDE closing while debugging, (I presume this is on 12.2) I would have told you to do the follow:

• Shut the IDE down.
• run regedit
• goto this key: HKEY_CURRENT_USER\Software\Embarcadero\BDS\23.0\Debugging
• add a string entry (if it is not there ) called HighlightDebugWindows and then set the value to False
• now start the IDE and see if the same problem occurs.
