Your claim seems to be that the Georgia Secretary of State (a staunch Republican and Trump supporter) along with the governor managed to pull off a huge operation to secretly change the results of the election (which would have involved hundreds of people and require that none of them speak out). That's a really outlandish claim, and requires supporting evidence, of which you have none.
I would prefer not to believe the election was stolen. I wanted Trump out, and Biden seems a reasonable replacement. I also debunked a number of the fallacious statistical 'proofs' the election was stolen. Believe me I would like nothing better than to believe everything is fine. But especially Navarro's report makes me unable to dismiss the allegations off hand with a clean conscience. I've also looked into the PA court's reasons for dismissing Trump's lawsuit from back in Sept, and the reasoning is all based on technicalities and does not address the substance of the concern that the loosening of the rules has opened the door to major fraud. The fact all the coverage of the lawsuits is frivolous dismissal or even in some cases the courts rule in favor does nothing to set my mind at ease.
Are there other, more credible, sources that are influencing your thinking? There is zero evidence supporting the claim of widespread fraud. Unless you have some evidence of some kind, it really seems like you would prefer to believe there is some vast conspiracy and you are writing off all the evidence to the contrary.
When I look for articles explaining why the lawsuits are rejected en mass, every article I have found is very hand wavy, stating the judges are appointed by Trump so we should expect them to be unbiased. However, no one actually dogs into the opinions or takes the reason why the election seems highly suspicious seriously.
To pick out one specific piece of evidence, in PA they found 200k more votes than voters, which is more than enough to change the result for that state. The counts are all from state government databases.

Navarro has over 50 such claims linked in his report, totalling over 3M potentially fraudulent votes. Regardless of what you think of the man, the evidence itself I find hard to set aside, even though I am like you and would tend towards dismissing Navarro as a partisan hack. But when he has laid out the claimed evidence like this in detail I must at least give it a spot check and the spot checks hold up so far.

You claim that the "spot checks hold up", but the one example you chose to cite (presumably one of the ones you believe holds up) falls apart with just a tiny bit of research.
The verification process in Georgia involved physically counting all of the paper ballots. The Dominion machines were totally uninvolved in the hand-recount (and, unsurprisingly, the hand-recount found that the original machine tally was extremely accurate)
Again, I think it's pretty clear you don't understand what role the machines actually play in the voting process.
