I've been following the Asrock problems with interest since they really started to be talked about, I've been using an Asrock B650I mini iTX board myself since around alte Feb early March ....but the key difference is I have been using it with a 7900X3D, so not a 9000 series chip and I haven't had any problems I also have never updated the Bios, which is on 3.15 iirc. From what I can tell though it's still very unclear weather the latest Bios actually does resolve the issue, the thing is, there is a good chance that people who update to it and still suffer chip deaths have already done the damage on the older Bios ...so it's tough to say right now. All we can really do at the moment is take Asrock's word for it ...and I wouldn't do that 
I certainly wouldn't put a 9000 series chip into my board though, at least not without flashing to Bios 3.4 first on my 7000 series.
