Also having persistent AIDA64 program freezes while monitoring sensors, same behaviour on x570 and x670e systems and ongoing since at least March like OP and still when testing todays 8.35.8405 beta.
Tested running SAFE/SAFEST, disabling GPU, MB, Voltage, low level SM BUS monitoring, basically exhausted all imaginable options.
Any ideas to solve this before renewing my maintenance period much appreciated?
