The bill was a huge concession from Democrats since it didn't include a path to citizenship for DACA and the bulk of the partisan elements of the bill were Republican ideas.
Okay, said the democrats, and drew up a bill that gives Ukraine money (something that most of America wants, and is just generally a good return on investment), gives Israel some money (a bipartisan thing that pretty much only part of the democrat progressive movement gets upset about), and a policy for the boarder that is damn near closing it, a huge concession from democrats who seemed to brush off border worries for so long. Democrats literally said, "Fine, we will do exactly what you want, and maybe you are right we should be doing this"
Republicans shut it down. Why? Ask them: They are admitting behind closed doors that they simply did not want to "help" Biden.
Remember, they consider improving situations they care about to be a bad thing when the "wrong" team is in charge. They don't care that they don't govern, and their voters actively seem to agree that governing at all while the "other team" is in charge is unacceptable.
