Google core update

What changes should I do in my website to recover it from Google core update. It had almost 200k traffic but after update almost 90% of traffic gone. Website has almost 300 Articles.

Wait till the update is rolled out, Till then If you have any AI content remove it and improve your EEAT.

You should wait until the update is over. meanwhile, you can delete any copy-paste or AI-written content.

When will the update be completely rolled out
