The affidavits that the government filed to get the Fulton County search warrant were published, and they contain a lot of seriously questionable assertions and "evidence". But that's not the most damning problem with the warrant or with this case as a whole.
The big problem is that there can't possibly be any crimes to prosecute, because the statute of limitations for 2020 election crimes, if there were any, has already passed.
I should also point out that there is one theoretically possible way the statute of limitations issue wouldn't apply, but it is extremely unlikely here. That is if something had happened to stop the clock for a particular defendant, such as a (possibly still sealed) indictment that had previously been issued.
But that almost certainly would have been mentioned (probably with details redacted) in the warrant affidavits, and there was nothing there to suggest anything like this.
