I've had that problem too, I was able to take the muslin off and just move the wand around to stop any hops blocking the syphon. But now I just dry hop with pellets or use a hop bag as it was infuriating

I'd drink it quick, if it is oxidised then the hops will go first they tend to drop off quick. I once bottled an IPA and my bottling wand had a hole in it, it sucked in air for every bottle. Beer tasted like shite after 8 weeks
If it's just a litre or so you might well be fine
