Random freezing? Even when i open calendar?

Hi. I've been having problems with the game since months. I was getting random freezing on the game and i neede to end task it and login again. My computer is strong.
I did tried:

Fresh downloaded client.
Without addons.
Lower settings.
Video drivers update + windows.
Change folder name or move it to another disk.
Stop antivirus program.
Checked my comp's temperature. No problem.
Lui errors dont give anything before freez.

And right now when i open the Calendar i'm getting freez right away. That started 2 days ago.

Nevermind, it's a global issue, not client-side. Probably nothing you can do to fix it.

I am having the same issue. Although what I get is a freeze of like 5 seconds then it will resume.

So, there is no fix on that freezing? I didnt had this problem 1 year ago. I don't know. It's really....

I am also experiencing the same issue. It only happens on one Character, all my other characters can open the calendar just fine, and all events load.

Steps attempted:
- Deleted Cache folder
- Fresh reinstall of WOW game
- Logged in on a completely different machine from which I have never logged on before, still happens.
- Disabled all Addons
- Left the guild (to avoid guild events clutter)
- Lowered graphical settings

This makes me believe that the issue lies somewhere on the server side. I am not able to see any particular LUA errors, however checking the FRAME logs I can see the following:

12/28 18:54:52.349 Loading add-on Blizzard_Calendar
12/28 18:54:52.349 ** Loading table of contents InterfaceAddOnsBlizzard_CalendarBlizzard_Calendar. toc
12/28 18:54:52.349 ++ Loading file InterfaceAddOnsBlizzard_CalendarBlizzard_Calendar. xml
12/28 18:54:52.349 Frame CalendarViewEventFrame: Unknown function CalendarViewEventFrame_OnUpdate in element OnUpdate

So it looks like it has issues when attempting to update the calendar. As to the reason why it's only localized on one single character, I can't say.

Yeah and it seems that only a certain amount of people are experiencing this when opening the calendar and maybe it's localized on 1 single character is because of the raid/dungeon lockouts? Since you have more lockouts on 1 character than the others
