TIL as a normal Ubuntu user, you don’t get quick and high-quality security updates.

“Liking winter” does not mean “liking the cold”.
It’s also winter inside your living room.

It’s always in relation to a frame of reference.
Compared to earth, you’re standing still, so your time passes at the same rate as earth time.
Compared to Sagittarius A, you’re moving through space, so your time passes slower than that of Sagittarius A.

“We can’t send e-mails farther than 500 miles”

You can’t go faster than light because time and space are basically the same thing, and you’re always moving through both of them together at a constant rate.
When you stand still, you move only through time, at the top speed of one second per second.
When you start moving through space, your speed doesn’t change, only your direction. (You can visualize it as an arrow showing your speed that stays the same length, but rotates in a coordinate system from the time axis towards the perpendicular space axis.) So the faster you move through space, the slower you move through time.
At light speed, you’re moving only through space. Your movement through time is zero, so time stops for you.
Going faster through space would mean going back in time, which would break causality.

The one where OneDrive moves all your data to the cloud without asking, then warns you you’re running out of cloud storage space, and when you then disable it, it deletes your stuff from the cloud without moving it back to your disk.
That one’s good fun for the whole family!

Or the one where OneDrive in its default config uploads your Documents folder to the cloud.
And Outlook 2019 in its default configuration stores the .pst file containing your e-mails in the Documents folder.
And Outlook .pst files get corrupted when you access them from inside OneDrive.
So a default MS Office install can corrupt your e-mails if you click “yes” on everything Microsoft “recommends”.

This little guy needs to be in there:

This looks like a hardware issue.
I’d guess at overheating, or an error with the CPU’s energy management.
First thing I’d do is look if there’s a BIOS update available.
Then install lm-sensors (there’s also a GUI frontend called psensor and a gnome shell extension) to show CPU temperature, and check if they’re too high. If they aren’t, you could set your CPU to always use max power and see if that fixes it, but it will reduce battery life.
Or try a different distro from a live USB and see if that makes a difference.
