You can add a litte more sealant. It will eventually stop

That sidewall looks weird. Have you been riding with it under pressured

Looks like factory defect to me

If that’s the worst of the damage, you might be able to run a tube in that tire to get some more miles out of it.

The sidewall looked damaged my guess is that you have riding under psi to cause that.

I would replace it. As a bike mechanic I cannot say that is safe to ride. It’s been damaged by riding too low pressure. That whole ring is compromised. It would blow in a spectacular fashion.
I had a tire of mine blow catastrophically , thankfully I had noticed a bump and my riding partner behind me saw a bulge at about the same time. So I immediately pulled to the shoulder, jumped off my bike and as I bent over to look at the huge bulge like a giant 4×6 inch blister explode and spray sealant in my face. Thankfully I had sunglasses on. The tread has separated from the sidewall for about 6 inches and I would have been riding on the rim at 25 mph…

Time to get a tube: that’ll fix all the problems in this picture for as long as this tire holds up. The tread looks good. Plus, that way, you can ditch the sealant!
In short: yes, that sidewall looks pretty damaged. I’d gamble it may not reliably hold air with just sealant.

I’m also running Panaracer tires (Gravelking slick 35mm). They have about 2,600 km on them and they show exactly the same bubbles (or maybe even worse) than the ones in your photo. Perhaps it’s unsafe, as others have said, but I continue to run them with fresh sealant. I replace the sealant every two months or so, and I make sure to spin them slowly and quickly at vertical and horizontal angles to make sure the sealant has spread around. Today I measured pressure before and after a long partly gravel ride and there was virtually no pressure lost after 145 minutes.
EDIT: On second glance at your photo, I would say the consistent stress line on your sidewall is not apparent on my tires. My sidewalls are just very thin-cased with bubbles dotted around with no particular pattern. I think that stress line makes a failure on your tires more likely but I am not an expert on that.
