What is going on with this Nevada election @realDonaldTrump ?

Republicans that voted for me are finding out that their ballots have been “voided.” On top of that, ballot harvesting is being allowed in my primary...but ONLY by those the state hand selects to do it. This is FRAUD! https://twitter.com/andrewangelcg/status/1264611306654449664

This is me. I checked this site 2 weeks ago to make sure my voting history was correct, now it’s gone and they’re saying I’m ineligible to vote. What is going on here?
