I went from 100k views to 0 what happened?

TLDR; I’m not a big content creator or influencer, I have like 2k followers but I typically average 1-10k views per video and some even have 100k, now, I recently changed my username and unfollowed a bunch of people in attempt to clear my account and stuff you know? And now, I get like maybe 4 views after 24 hours, so what’s happening? Is it cause of the sudden changes I did? Did I do something to piss off the TikTok algorithm, I checked I don’t have any reports or anything soooo what can I do? What could have caused this and how can I solve it? I really don’t want to change accounts cause I worked so hard in this account and I don’t want to waste it 😞
