Good spotting, ra_alfaomega! That happened to be the time when I started to migrate from my laptop and desktop. I did a fresh installation and with the latest Nvidia drivers at that time, F@H wouldn't run (https://foldingforum.org/viewtopic.php?f=80&t=29276&start=285). However, the latest driver seems to work most of the time which is good news I am currently waiting for the next release of Nvidia driver or the next version of FahCore_21 to be able to fold on my dual GTX 1070s stably (https://foldingforum.org/viewtopic.php?f=24&t=29633). Unfortunately, I can't use the old drivers as some content-creation applications that I use on a daily bases requires the latest drivers I am (impatiently) waiting for that day which I hope is within this month as I do miss folding on my computer but can't afford any instabilities as it will have a detrimental effect on my daily work.
