How to restore normal operation?
How to back up your data before resetting everything?

What's the battery level? It might start to boot, see that the battery
is low, and shut off. Have you tried putting the phone on its charger,
wait 10 minutes, or so, to let the phone take some charge, and then
tried booting?

Just because the battery level indicator says 45%, or something that
looks like a sufficient power level, that does not indicate the capacity
of the battery, just its voltage. If the battery is old, and cannot
hold much of a charge anymore (not as many coloumbs), it can show a good
charge (by voltage), but not handle the load (by capacity).

The Cat S60 was introduced back in 2016. Maybe you're still trying to
use the ancient battery, or just using a defective battery that won't
much of a charge.

Getting to the recovery screen doesn't say that you then managed to
normally boot the phone. The recovery screen doesn't take much power
since none of the radios are yet active to consume power, and no
services and no apps have yet been loaded.

Alas, the Cat S60 was designed with a non-serviceable battery. You have
to crack open the case to replace the battery. Nowhere as easy as for a
user-serviceable battery where you just flip open the backplate to pop
out and old battery to pop in a new battery. Be sure when buying a new
battery that you don't get stuck with a counterfeit one, or a cheap
knock off.

You break the seal to get inside. The phone won't be water resistent
anymore. I don't know if the screws are the same length, so lay them
out on a piece of paper where you've drawn an outline of the phone, and
place the screws on the drawing where you removed them. You have to
disassemble the case because the battery has a flex foil connector, not
simple contacts as with user-serviceable batteries.

If you don't feel confident you can do the disassembly, battery replace,
and re-assembly, take the phone to a shop that will replace the battery
for you. Ask whose battery they will use. Tell them not to use a
counterfeit or cheap battery; else, you'll be replacing the battery a
lot sooner.

No, battery is 100% charged and with power-cable connected
I don't think the battery is responsible
I think it's a software problem, a few days ago I installed a bunch of
new programs like Coyote GPS and similar, this is the only recent change
I can think of
The reboot of the phone was performed frequently because usually the
phone ran out of battery and therefore the reboot was certainly
performed recently
In reality the battery is replaceable, you just need to be a little
careful when opening the back shell of the phone, I replaced it once
about six months ago and recently it lasted almost two days (I always
turn off GPS and WiFi when not used)

I've had this exact problem caused by a bad battery (on a Galaxy Note 4).
Booting is quite power demanding from the battery, and on my battery the
voltage would sag enough to reset, hence the bootloop. The actual battery
was not empty - charged fine, voltage looked good etc, I think the phone
would have run had it been able to boot - it's just it couldn't handle the
current draw of booting[*].

I changed it for a new battery, problem solved.

[*] hence Apple's 'batterygate', where they slowed the phone to reduce the
current draw on elderly batteries to avoid them dropping out under load.

Yes, of course, I believe you
But in my case this is not the case, and I say this for two reasons

The first is that I replaced the battery six months ago with a new one

The second is that until the problem occurred when I restarted the phone
it lasted almost two days with normal use of the phone

And this seems to me to be an indicator of good battery condition
