I can confirm that in my case, all the suggested alternatives in this thread didn't work (the ones that were applicable to my use-case anyway).
In the end, I threw my hands up and did an RMA. And that was over a month ago. It seems to have solved the isssue. The processor I had previously and its replacement were different batches; the former being from 2019 and the latter from Feb. 2020. It seems to me that AMD ironed out some issues with processors and I got lucky with the replacement. Or it could just be some tiny variations in fabrication. I can never be sure. But my machine has been up since the RMA without any crashes.
