I discussed this in more detail with Tom in another recent thread, which I saw you read at least some of, maybe not all.
The Afghanistan withdrawal and the corresponding negotiation with the Taliban were all decided by the Trump administration, which Biden then decided not to reverse, so let's call it a joint responsibility of both. Tom did make an attempt to try and pretend that somehow Trump would've handled things better at the actual moment of withdrawal, but the best argument he could come up with, about a lack of air cover, was easy to counter, because the strengthening of the Taliban and crumbling of the Afghan army started pretty much immediately after the agreement with the Taliban was reached, in early 2020. Trump didn't do anything in the remainder of his term to change that. Could Biden have changed that - sure, but only by undoing the decision and deciding to stay after all, in which case the Republicans would've howled as well. In other words, blaming Biden but not Trump for the Afghanistan withdrawal is a first grader level of logic, which would also make Trump solely responsible for the entirety of the Covid pandemic and its economic impact because hey, he was president when it started.
Which leads us into the next point, inflation - once again, trying to pretend that the inflation can simply be blamed on Biden and that's it, end of discussion, is an oversimplification that's quite honestly beneath you.
Your last two points about illegal immigration and Biden's lack of bipartisanship are a bit more complex - but, as I also discussed with Tom, it is rather remarkable after all the fuss Republicans have been kicking up about illegal immigration under Biden, that the number of illegal immigrants is... precisely the same as it was twenty years ago during the Bush presidency. And the Republicans, or at least the ones following Trump's lead which recently has become very nearly all of them, have shown no goodwill whatsoever to cooperate with Biden, whether on the border or anything else. Certainly, he's also been under pressure from progressive Democrats to cooperate less with the Republicans than he might've otherwise liked to do, there is obviously polarization on both sides, but there's still not all that much more that he realistically could have achieved with Trump shouting from the sidelines and torching the career of any Republican willing to play ball with him.
Though that said, Trump also torched the careers of Republicans who achieved more than Trump ever did, both in terms of electoral victories and in terms of red meat conservative policies, i.e. Ron DeSantis.
Voting for a Republican president is one thing, voting for a Trumpist president another thing entirely. It's true that it really doesn't matter who the Democratic candidate is, when the Republican candidate is Trump - the Republicans had their chance to select a candidate that wasn't a complete pile of shit but they refused to do so.
