When calling up the email template window in dark mode, the text of the email cannot be seen. Also, just about any operation in this window (selecting from drop down, etc.) causes a crash. Also, to call up the window when the orders panel is active, the email icon in the toolbar has to be clicked twice. Using Beta 45 (also happens in 44).
Also, as I am assume that the crash comes from some special values in your Me Card in the Contacts Application, can you send me a (private) message with your exported Me card or a screenshot of it?
Previously, I don’t remember allowing access to my contacts on 1st launch. Maybe this is what started the problems. Something for you to check into.
I have used many of the GS8 betas without this problem every showing up.
