If you find any tiny bulbs around the roots, that will be it.
Almost impossible to eradicate but it will die-back completely soon (and come back next winter.) If it is that, try not to cultivate the soil in the areas where it grows or move plants from there to other parts of your garden as this will spread those tiny bulbs. Weed killer isn't very effective I'm afraid but the types where you rub a gel on the leaves by hand may work a lttle better than a spray.
A trowel in the hand is worth a thousand lost under a bush.
@Obelixx It's always more difficult when plants are removed and photographed rather than leaving in place, isn't it?! Celandine is quite variable in leaf shape and many variants have markings too - mine look like OPs. I guess it comes down to whether violet or yellow flowers!

Looks like celadine to me too. It does look good in spring and does die down, but will gradually take over. I let it flower them pull it up in clumps. Doesn't eradicate it, but keeps it a bit under control.
Celendine, it’s a bit of a losing battle, I just dig it out when it gets too much, you have to get every little white bulb out. Don’t put it in your compost bin, it never dies! The garden here was covered, I’ve managed to eradicate from important places.

They can run rampant when happy but are good for difficult, shady places and for pollinators.
