Other details

Latest working version build 1675

Something similar also happens when I try to open the About section under Settings.

[StillInSearchOfACoolNewUsername]

Same happens here, now by doing anything. I've heard that they are making some experiments with the new cloudflare. Don't worry too much about it. If you have backups, ( I suggest enabling the auto-backup if you didn't already) try installing the older version, or like in my case, having the stable version ready for situations like this.

A quick fix is to change your prefered time and date format under General settings.

Having it on the default setting (System default ) causes the crash.

Any other is fine and will make About and other places which crashes, work again.
