Window froze after changing a time block ("repeating daily") in calendar.

@ChLi Please wait until some person with more knowledge on restore of Mail and Calendar can help.
I do not use Mail and Calendar. I am more familiar with browser-only testing.

ChLi

@DoctorG Is there anyway that I could fix this by myself? Because it's kind of urgent and I don't know about the dates without calendar.

Hi, I flagged this thread to get moved to the mail/calendar section, there often mail developers read threads.

Cheers, mib

@ChLi
You can try to login to your webmail account and delete the broken calendar entry.

Maybe this remove the start block, this is just guessing but at least you can work in the online calendar until a developer steps by to help.

@ChLi One thing you can try to do to confirm if it is the calendar data that is causing problems is to move the calendar database out of your profile.

Open your profile folder (If you don't know the path you can find it on vivaldi://about page).
Shut down Vivaldi.
Locate the calendar database file. It is called Calendar with no extension.
Rename or move that file to a safe location.
Start Vivaldi.

Vivaldi should now start with a completely empty calendar. If it starts up ok then the source of your problems is likely some broken data in the database.

As I understand from previous answers, you are using remote calendar(s) and they work in a new profile. In that case you could do the setup in a new profile, and then copy the calendar database to the original profile. Or alternatively just add the calendars again in the main profile after removing the old database file. If indeed the reason for Vivaldi not starting is broken data in the database then there is a good chance this will solve your problem.

In case you have local calendars then the problem might be trickier.

Hope this will help,

@eggert Thank you so much. It no longer freezes now after I renamed the old file. Though, is there anyway that I could transfer the stuff from my old calendar to the new one?

ChLi

@ChLi Okay, nevermind. I deleted a task block that was due in 1969 then it worked perfectly again.
