Help I think I got shadow banned- maybe?

I recently started making shorts again after getting my channel up to a bit over 9 thousand subscribers a couple and since I had stopped making videos, I had lost about a thousand subscribers. Anyway, in the past month I’ve been consistently posting almost every day. I’ve gotten to the point where I was getting around 20k views a video and over a hundred subscribers a day. I even got past my original subscriber count. But one day I posted this video. It started off only at 500 views, but every hour it randomly would get another hundred views all at once. Then in the evening it went up to 6k. Then at 1:30am it skyrocketed up to 23k and I got 430 subscribers in that time, which is the most I have ever gotten in a day. Then all of a sudden my views started decreasing around 7am, which is normal for my videos. But usually after I most my video for the day it went to 100 views and just stopped for like 5 hours, completely different from the rest of my videos. After waiting long enough I deleted it and reuploaded it- nothing. I got maybe 80 views in a few hours before I tried reuploading it again. Basically for some reason after having one of my best days, my views just plummeted and I am getting none. When a video wasn’t actively getting a bunch of views, I was at least getting about 100ish or more an hour, but now since 10am yesterday, it’s barely gone above 20 views an hour. What happened? Why aren’t my shorts getting shown to anyone anymore. My engagement is good but they just aren’t getting shown to anyone. Should I wait more than a full day to see if the video can pick up? Is there a way I can contact someone at YouTube to find out what’s going on? I’m just really lost and demoralized because I’ve been trying so hard editing all my videos, spending about an hour to 2 a day just on a 30 second video. Any help or suggestions would be great. Thanks in advance

TLDR: I had my best day in term of subscribers and one of my best in views, but then my views just plummeted and I don’t know why
