Views on any new videos drastically low after going viral, what is that about?

I had a video go viral and then any videos I posted for about a week after that one also got decent views but then the past week and a half almost two weeks, my videos I’ve posted since have barely even been getting 100 views and it’s like they aren’t even being shown to my followers. The last two days every video I’ve posted gets like maybe 30-50 views and no likes with like 1 or 2 saves. My viral video and the videos around that time that did well are still getting views and engagement but it seems like anything I post now is dead.

ive heard some people say TikTok will like test new audiences after you go viral and maybe that’s what’s happening? My account is also in good standing so I know that’s not it either. it’s super frustrating
