I have the exact same issue on my PC, Ryzen 5 1600AF + B450 Aorus M, which is also with a 2nd Gen (Zen+) CPU like your 2700X. However, in my case, I had driver version 5.24.0.0 installed and couldn't update to 5.26.0.0, because update always failed. 5.26.0.0 is included with AMD Chipset drivers 6.01.25.342, and only after uninstalling 5.24.0.0, I found out on release notes that there was a known issue where installation of AMD PSP driver could fail on Ryzen 2000 processors, which is exactly what happened.
So I made the mistake of uninstalling version 5.24.0.0, and now I can't update past 4.11.0.0, which is a very outdated stock driver from november 2019. Also, the device name changed from "AMD PSP 2.0 Device" to "AMD PSP 3.0 Device". I mean, I can update occasionally, but driver will be corrupted and won't be loaded like yu described. I tried updating to 5.24.0.0 again, but it won't update anymore.
I tried installing several versions, like 5.25.0.0 that came with chipset drivers provided by my motherboard manufacturer, but no luck, it's permanently stuck on 4.11.0.0.
