Yes, I had the same problem. Check out if there is a (cumulative) Windows update. After installing the Windows update and a reboot, it worked again for me. Last fiddled with by S485122 on 20220831 at 21:12 Reason: no need to quote the rest

When having a custom affinity block in local.txt on Linux, everything there seems to get mangled with:

Prime95 knows nothing about htop's (or Linux's) logical CPU numbering.
Prime95 relies on hwloc's numbering. Run a benchmark (and abort it). The hwloc topology is written to results.bench.txt. What does that look like?

Unfortunately, I had to abort it, I would have liked to perform the benchmark as usual, but it got stuck:

Please set "KindVerbosity=1" in prime.txt and get the hwloc topology again. Thanks.
Then in local.txt try "Core0Ranking=1" and "Core15Ranking=1" Last fiddled with by Prime95 on 20220904 at 13:45

I may try linking with hwloc 2.8.0 or 2.7.1 for you to test. All those local.txt entries basically overrode the information returned by hwloc. Prime95 though has a bug  it should not have hung.
