I'm going to say that you've got a serious lack of understanding on whats happening here, and that you need to tone down on the attitude.
The stuttering was limited to very specific setups running windows 10 and 11 with TPM enabled before installing the OS - and not all users had the issue, because it was specific to certain software and hardware combinations.
There is zero danger from a bios update it's common practice for modern hardware.
You have no right to insult anyone here or call people condescending with the childish behaviour you're showing.
You've got one of, if not THE worst motherboard every released for socket AM4 with well known VRM overheating issues that cause serious performance problems, and you didnt list your RAM or it's rated speeds/current speeds and ryzen 3000 is really well known for both being fussy with RAM settings and also suffering serious performance problems if the RAM isn't fast enough.
As to the motherboard:

There is one worse board - which is also MSI and released at the same time

At 12:29 in the video, he specifically mentions the only reason the x570-A Pro ran as cold as it did (at second hottest) is that it throttled the CPU.
and then at 14:48 he has a specific rant about that motherboard in particular, of all the ones tested
In their testing, the CPU was forced down to 550Mhz. Using just 55 watts of power.

So maybe, maaaaybe it's that you bought a terrible motherboard but instead of asking for help or providing relevant information you get angry at people?
You may have a lower wattage CPU than they're using, but they're also using brand new boards in temperature controlled environments. Once add in higher ambient temps, a poorly cooled PC or worn out thermal pads and you'll find your board is genuinely unusable on all but the lowest wattage CPU's at low loads, it's simply garbage.
