my website lost all traffic

hello my website has lost almost 90% of its organic traffic due to poor rankings on google I need your advice as rank math plugin provider, before installing wp rocket plugin my website was ranking higher and was not having this problem but since installing the plugin website has been performing very bad, I tried troubleshooting and check my google search console report it shows no issues and no manual actions or security problem. I installed the wp rocket plugin to help speed my website and fix core web vitals on September 18, 2022, and since installing this plugin my website rankings have become worse though the seo performance is good on page speed insights with 99% on mobile and 100% on desktop, this doesn’t help me since any new article I publish it ranks very low in the last page of google serps or it even doesn’t show up yesterday all my articles even those with less competition disappeared overnight on google I’m started to worried.
I’m not sure if the wp rocket is the one which causes this problem but i do suspect it, since this problem started after using this plugin help me with any advice
