Краткий перевод: по пути C:\Users\ХХХ\Appdata\Roaming\Microsoft\Protect\ удалить дважды скрытую папку.

So...Using that info, I went to the path "C:\Users\John\Appdata\Roaming\Microsoft\Protect\" and found one folder with a random guid that was created days ago. lsass.exe was currently still in a 'stuck' state, when I deleted this guid folder, and another one was immediately created with a new guid. The next step is probably unnecessary, but I deleted the newly created guid folder as well, and this time it did not respawn. lsass.exe processor time was back to normal. I attempted to close chrome, at which point it closed properly. I reopened chrome, observed lsass use some cpu for about 10 seconds, then stop. I closed chrome, and the process terminated properly yet again. I then reopened chrome to observe the same behavior as previous (normal behavior).

So, conclusion, the folder located at "C:\Users\<username>\appdata\roaming\microsoft\protect\<guid>" must be deleted.
