Were this about handing off Ukraine support to Europe, it would have involved talks with European leaders, and US support would have been withdrawn at some future date so Europe can pick up the slack beforehand, ideally slowly phasing it out. Instead, Trump stopped it immediately and without warning. I suppose it could be a tantrum over Zelensky's failure to provide dirt on Biden for the 2020 election as much as it could be about trying to ingratiate himself to Putin, though.
