Google shadowban

Hi guys,
can someone explain what happened to my website (google search console data in the screenshot), I've been recieving some traffic but since mid september I haven't recieved any traffic it seems like a shadowban
the website is a one page cpa site, do you have any idea why that might happen and what I can do to fix it or prevent it in the future??

this is pretty common with most of the new websites nowadays, both built on top of expired or new domains,
mainly happening because of poor on-page & content, poor eat, etc...

investing in some decent links & better content helped me get some websites out this type of google filters,
both for the indexing/crawling limitations where it could be stuck in XX number of indexed pages (could be up to thousands sometimes) and ranking
