Don’t attempt this on a bike tyre, you’ll be walking home if you do.

No its not. It's just not for you. I guess you had a less than satisfactory experience.
Only this morning I rode over a hedgehog. Or it might have been the big heap of blackthorn cuttings. 3 holes, all sealed. Noticeable but more than acceptable pressure loss meant that I didn't bother getting the pump out until the coffee stop. Less hassle to me.
Maybe a bteer comment might have been "for me Tubeless is a poor idea on a road bike."
Just a thought.

if the tyre was initially inflated using CO2 then this can react to form a weak acid and this weak acid can react with latex-based sealants so that the sealant 'dries out' (cures) abnormally quickly.
There are many, many, potential pitfalls with 'road tubeless'.

I have to say that i don't get this problem on my gravel bike with WTB 42 nano. But i think they more have puncture protection in the tyre
My experience with the Schwalbe Pro One is that they puncture easily and the sealant fixes it. The problem with that is that if there is a problem with the sealant or the hole/tear is too big then it doesn't work. The upside is that they roll really well. The may end up being a summer solution for me

This was a new tyre three weeks ago, Schwalbe Pro One and Stans Sealant. Any idea why this would dry up so quickly?

I try to only fit tubeless tyres in the garage when I have patience to spare. First fit the tyre with a tube on the intended wheel, make sure it 'pops' properly onto the rim bed. over inflate and leave for few days, some tyres are initially almost impossibe to lift over the rim are now a bit easier, so the bead has stretched a touch.
Delate fully, and this is important I find, the tyre must stay up on the rim bed. If it drops into the well, add another layer of tape, repeat if necessary.
Take out the tube and fit valve with no core and inflate (track pump sometimes or a blast from compressor)...etc.
If it still won't inflate, I put the tube back in and pop the tyre again. Deflate and now ONLY push one bead down and lift only that side over the rim to retrieve the tube. Now try to inflate tubeless, and the air pressure only needs to move 'half' a tyre. I generally paint a bit a sealant on this bead first too, and it's worked in all but one stubborn case.
Bit of faff, and I don't think it practical on the road. I have not yet had non sealing puncture but if I did and my tyre unseated, I couldn't be sure a normal pump/CO2 would definitely pop it back, so always carry tube. I could repeat all of the above, but in practice would just leave the tube in until later. Not happened in three years but that's the plan
