Date&time in panel

Today I faced a little problem in panel. Clock and date disappear after system has loaded. When system is loading date and time are shown for a second or less. But then date and time disappear.

I've deleted an applet from panel and add it again, but date and time didn't appear.
I had tried to switch off and on clock and date it made no change at all.

What can do to make date and time are shown?

P.S. English not my native language, so excuse me for mistakes.

Hey @cyril, it's nice to see you again.

Does a dialog along the lines of "[such-and-such a panel applet] was unable to load" appear soon after the system starts up?

If not, when you add another Clock Applet to the panel, does a dialog come up at that point?

The answer is no twice. Some times I have problem with loading of sound applet, but I believe I didn't see any alert about problems with loading applets for some time.

OK, then, go to your home directory and copy the contents of your .xsession-errors file into a post here.

I also have .xsession-errors.old file if it's important information.

No, I don't think I need the .old file yet.

A quick glance reveals that: Of course the dialog that I described above shouldn't appear. The problem lies within the Clock Indicator. I forgot Ubuntu MATE ships with that; I always disable the indicators, personally.

I have a question @cyril: Have you done anything with the Evolution mail client lately that might involve the Calendars feature? Because this error looks like a problem with Evolution, partly.

(Side note: I can't really read Belarusian, but I quite strongly suspect that "ΠŸΡ€Π΅Π΄ΡƒΠΏΡ€Π΅ΠΆΠ΄Π΅Π½ΠΈΠ΅ ΠΌΠ΅Π½Π΅Π΄ΠΆΠ΅Ρ€Π° ΠΎΠΊΠΎΠ½" says "Window manager warning"! (Oh wait. It's Russian. Pardon me.)

there had been an error that messed up the indicator if the google account connected to Evolution had a task associated with it, that had a date assigned, if one removes the date I believe it should return after a restart, I think it's been a while I just don't use dates in google tasks anymore, maybe it happens with other types of accounts to, but I only have google accounts connected to Evolution

It's russian indeed. It's translated like "Windows manager alert".

Oh, I think you are on the right way.

I use Google accounts and Google calendar with one of it. I use Evolution in Ubuntu Mate for all my e-mails include Google and set up a Google calendar. And some days ago I had to change my smartphone. The old one has an Android 6, the new one has Android 10. So some things are new for me.
As I had to make a new record in calendar I found that there are several types of records now like meeting, task and reminder. Or however they name in english interface. So, I decided to try new type of record and also delete some of the old repeating records and create it again as new type.
After that I faced with problem. How can I solve my problem?

Basically I believe you remove the dates from tasks and restart I think, if that doesn't work I'll have to look into it, but somewhere on the forum it has been dealt with before

Many many thanks to you. I've deleted all new tasks and events I had created by my new smartphone and time&date panel appeared again. ))))))

After that I decided to create all the tasks and events I had deleted before in Evolution and I found that tasks I can create in Evolution only for personal calendar but not for Google calendar, however events and meetings I can create for both personal and Google calendar.

I believe my problem appeared because I created tasks by smartphone in Google calendar but Evolution doesn't accept tasks for Google calendar.
