Hey legends! How can I stop this leak between tyre and rim? The tubeless sealant doesn’t seem to plug it. Thanks!

Is the tyre damaged?
Are the tyre ad rim tubeless compatible?
It it actually a puncture (looks like it)? If so, these can be troublesome as it’s right on the bead, and a plug repair can interfere with the tyre seating. And you can’t patch it from the inside.
That said, you have a tubeless repair kit, right? Plugging it takes two minutes so just give it a try and see if it seats OK – sometimes they do ime.
If it’s not actually a punctured tyre, just unseated at that position, then I’d fully deflate it and check the rim is clean around that area (no need to take the tyre off or mess with sealant). Then just re-inflate and over-pressure it (do not exceed the max rating on the tyre) to see if it seats, that usually sorts out minor seating issues.
I’ve had one of these and helped someone else fix one like it as well. You need to stick a plug or bacon strip in there first, then get the wheel on its side and rock it back and forth to get a good amount of fluid over it. Generally this is too close to the rim for the fluid to get to on its own and you only get small splashes and no particles to plug it.
Remove tire, apply patch to area (on the inside of the tire) being careful not to overlap the bead, inflate to reseat and check for issues.
do you maybe smashed a curb and got a pinch flat? it happened to me and i plugged it right at the bead, been holding for 3000km
If this happened in conjunction with another flat, you may just have a piece of gravel between the bead and rim which creates too much of a gap for the tire to seat and the sealant to seal. I just had this issue last weekend. Pulled the tire off the bead and got the rock out. Tire sealed right up after that.
This looks like a pinch flat. Throw in a tire plug and ride on. Have a few tires I’ve ridden for the season w a plug there zero problems
Inner tube
Judging by the cracking that is around your knob on the top, I would say you’re tire is a little sun weathered which means that rubber isn’t as rubbery as it once was you could potentially fix it by using some patches, but it would be a lot easier. just get a new tire
I hate to say it, but it’s likely new tire time. Pinch flats along the rim are nearly impossible to plug as that part of the tire takes a lot load and flexes. If the threads are not damaged, you could try a plug or even gluing a tube path to the inside, but I have rarely been able to salvage a tire after that type of flat.
Deflate the tire then pop the bead all around then inflate the tire till the beads pop in again.
If that doesn’t improve it then I’d move onto the other suggestions here.
You may try with less pressure. To let the sealant “time” to dry…
If it’s a hole in the sidewall you can try to boot it with a patch on the inside. Get it sealed really good against the inside of the tire. The boot patch and sealant should do the trick. Otherwise? New tire time.
