When quitting Kleopatra it always crashes. You need only to start Kleopatra and close it again, no additional prerequisites.

Looking at the Windows "Problem reports" I saw that it lists many crashes of Kleopatra since 2024-06-19. An older Kleopatra (gpg4win-4.3.2-beta15, built on 2024-04-16) does not crash on exit. The next Kleopatra (gpg4win-4.3.2-beta23, built on 2024-07-05) does crash on exit. The reports point to the libkleo DLL.

Gpg4win-Beta-75:
Looks good, I see no "EXCEPTION_ACCESS_VIOLATION" after quitting any more.
Instead only: "process started at 14:11:03.007 has terminated with exit code 0"
