Umidity Alarm without being soak on water

I've already saw on older topics that it was a commom issue with A54, but i've never had that problem before yesterday. My phone was fine, but after falling on bathroom florr (that was dried btw), it's showing this warning everytime.

I've tried to clean witha brush, dried with cold hairdryer, let it be for 12h, clean the cache, but nothing is resolving the issue.

Anyone with the same problem?
