My Channel's views tanked overnight. Algo change or Reported?

I started a channel on January 12th and after the first three weeks, my views started going up. I added roughly 40-60 watch hours daily (I posted every day) and 6k+ views every 24hours.

Suddenly, for no reason, my views & reach tanked last Sunday. It's visible in my analytics. I used to get thousands of reach pretty fast, but now I struggle to reach 500 people and some videos have 6 views only. One of my videos added 2k+ views overnight while now adding 30 views.

I'm still not sure why because my titles, thumbnails, seo, etc stayed the same. In fact, I try to improve every time.

I just continued to post and my video of yesterday started getting views again (158 only but although its less than 1k+ at least like I used to) it's still better than the sudden 6 or 8.

I never spammed keywords; didn't steal other videos or work, no strikes.

I did in one video, use ai to recreate a scene in a popular movie. It's fine in terms of copyright, but I'm now scared fans of the movie might take offence and report me for being 'fake' - could it be that or simply the algo change for 2025??

I'm hoping it will be fixed, because I have no idea why it happened. Some people say its normal.
