My torch did this same thing previously, this model: https://www.amazon.com/gp/product/B011UIMXXC/

I had to throw it outside and use the fire extinguisher to get it out. What's hilarious is that mine looks nothing like yours, but the link to it now redirects to that one that is exactly yours. Mine was black and orange and from the brand Ideapro, but clearly it's the same company behind it.

I switched to the EurKitchen culinary torch after because it by design doesn't have the possibility of gases shooting out the wrong ways. This was two plus years back and I love it, would never switch back to the ones which connect to a can.
