If i debug will i loose any data from my website?

First time i installed Yoast plugin, then next day I couldn’t find my website, I did see some error, like unable to find the URL that you are trying, even WordPress I am unable to login. So I went into cpanel and deleted the plugin, then it was fine, later today I tried installing google site kit and It showed your website is facing a serious problem contact the administrator now, then again i went into cpanel and removed the plugin then it was fine.
