Have you tried under clocking and over voltage instead? Apparently the RX 5700 needs the power for stability? I thought it was exact same GPU as W5700 so I don't understand what that's about but that's what people say, try a lil extra power, a lil lower clock. If you remember it was stable with a specific driver version you can revert back but otherwise I feel like installing random drivers other than the latest is just a shot in the dark. (You can still go for it, I'd just be way too lazy to DDU, install, rinse and repeat especially if the problem is intermittent)
If you do decide to try random driver versions though, I wonder if the Radeon Pro software would install? Or would it not make a difference even if it did?
