I've had trouble with file sharing permissions settings before that felt like black magic to me (I never could figure out the inconsistencies after looking it up and trying over and over again). That was after wiping my HDD and reinstalling Windows as well - so same premise as you have. Thankfully my issue wasn't with Strive at least and I did get a workaround that's still "working" for me. Anyhow, I'm glad you got it working.
