Turn ignition on. Lights turn on. Press ignition hear a instant short-circuit sound and bike goes dead. No power no nothing.
Turn ignition on off. No power.
Immediate thought is fuse. I check all the fuses. Main FI etc all look fine.
Put key in ignition, it’s alive again. I don’t start it though.
Turn ignition off, check fuses again.
Put key in ignition bike dead.
Take the fuse out of the cable that leads to heated gloves. Bike comes back to life. Bike starts!
I think the cable to the heated gloves shorted the battery.
If that’s the case, would the fuse still be ok?
Would the battery reset after a few minutes?
At the moment the bike is on a battery optimiser and I’m not going to use the heated gloves tomorrow.

What’s a ‘short-circuit’ sound? Was it a ‘tick’ like a fuse blowing, a tap like a starter solenoid closing, or something else?

Is your main fuse right by the rest of them (often it’s closer to the battery, because it’s got to also protect the starter relay) and aside from being not-blown (how are you checking these fuses) is there any damage to the fuses or their holders?
I’d echo Jay’s suggestion of checking the battery terminals, and also any plugs/sockets between the battery and the ECU.
Does the bike now reliably power on when you turn the ignition on, or is it still a bit hit and miss? Does the clock still show the right time, has it remembered your trips etc.?

Why?

The fuse in the cable would have blown.

No, but a safety cut-out somewhere might have done. Your fiddling may have disturbed a loose-connection, too.
How old is the battery mine did similar when one of the battery cells started to give out, took me a while to find out it was the battery as it acted like a bad ground to start with
Water ingress or moisture around contacts/terminals are most difficult to diagnose especially with intermittent faults. If you ain’t checking it with a multimeter you’re proper wasting your time.
