I'd recommend going back to 1703, even if your system files don't have it I'm sure you can do so via mircosoft downloads. I've delayed mine to upgrade for 365 days that was months ago and I've not had a single crash since. Every time I've tried to upgrade to 1709 I freeze within a few days, then freeze with increasing frequency, until my system is completely unusable.
I am hoping to be able to skip version 1709 entirely and by the time I need to upgrade I can do whatever major version is next, which I'd hope doesn't have the issue (though it may have other issues).
