You're so passionate about this issue and yet haven't actually researched it.
That loan had not yet been approved by congress. This was for a 3rd billion dollar loan which would be conditioned on their commitment to rooting out corruption.

"As part of the United States’ commitment to working with international partners to ensure Ukraine has the support it needs to continue making progress on reforms, today I am pleased to announce that
President Obama, working with our Congress, intends to move forward with a third, $1 billion loan guarantee for Ukraine in the coming months.
This fulfills a U.S.
commitment to consider providing a third $1 billion loan guarantee in late 2015
if conditions warrant.
Today, I have had the opportunity to discuss with President Poroshenko and Prime Minister Yatsenyuk how the United States and Ukraine can use the third $1 billion U.S. loan guarantee to support continued progress in advancing reforms, including reforms that will be important to unlock international investment in Ukraine and lay the groundwork for return to growth.
The U.S. loan guarantee
will be conditioned on Ukraine’s progress on implementing its economic reform program, including of course adherence to the IMF’s program and concrete forward momentum in the ongoing fight against corruption."
Biden later communicated the same stance. It wasn't up to Biden. It was the police of the entire Obama administration and was ultimately approved by congress in 2016.
Not trying to be rude here, but you have gotten so much just factually incorrect.
Take your time and read up on the issue if you really want to understand what happened.
