I've had poetry sit there for minutes resolving dependencies at a previous company. I thought something was broken... it probably was... but it did eventually complete.
I've had poetry take so long that I've just deleted the whole cache/poetry list and reinstalled the packages rather than wait for poetry to figure out whatever dependency hell it found itself in. I switched to uv the minute i tried it out
You don't have that problem with Poetry. You go make a cup of coffee for a couple minutes, and it's usually done when you come back.
