HI @karl-hermann_5164 sorry about the crashes. When this happens, do you get the crash reporter dialog? If so, do you fill it out with your email address? I looked in our system for reports with the email you use for this forum account, but nothing came up. Do you use a different email for your Creative Cloud account? Feel free to DM that to me and I can can search our system.
Thanks,
