GSC Page Experience Going Down Since Using LS

Hi Team,

I recently switched to LiteSpeed plugin from WPRocket 3 days back & since then, I have seen a huge drop in my GSC Page Experience report for Good URL & Impressions on Goodurl & is still going down each day. The page speed score on both mobile & desktop is above 90+ but still, this issue.
