Same issue here too, if you look at the crash logs in the generated CrashContext.runtime-xml, you can see the line:My guess is something on startup is generating a date with "todays date - 1 year" and not being clever about it. Then, because we're in a leap year, Feb 29 was not a valid date in 2019.Edit: A number of people in the thread are reporting that changing the system date to something other than Feb 29 solves the issue.
