Well, that wound entirely depend on the severity of the eruption - species could get fucked & if most of the species die on the other side of the world that’s a global problem (eg one of the biggest such eruptions, wiki/Siberian_Traps, causing wiki/Permian-Triassic_extinction_event).
With volcanic eruptions the atmosphere could get full of greenhouse gases pushing the planet into extremes of dry & wet, and also heating atmosphere to the point of forests being burnt off entirely, oceans could acidify killing most things, and sunlight reaching the surface could get greatly diminished making growing things hard, etc.
The above linked event had the giant volcano/basin erupting for 200k years & the inhospitable enrolment lasting for 8 million years (iirc, -ish).
(Compared to this - this is what ppl don’t realise how much CO2 are we pumping into the atmosphere in just years!!)
Yellowstone would probably not be that bad, but it could affect plant growth globally, as well as mortality rates (heavy metal vapours & such).
Also things like air travel would basically stop with current engines. Nations would go to wars over food & water, mass migrations, changes in how humans live (types of houses, if even above ground, what we wear, how we filter the air, what we eat, where we gather, etc).

As a bonus, Yellowstone vs Siberia:
