Congrats. Glad you got it tesolved. I would recommend maybe doing a server backup if your thinking on trying a plugin install.
Though tbh you should be fine as long as you enter the plugin install correctly. With the plugin you were trying to install now come to think of it may need an update. Iirc now it showed last activity was feb 2022? if so it is potentially a year out of date and changes since then mau have broken the plugin.
Confirmed
I would recommend looking over plugin Category and see if any plugins may peak your interest.

Main thing avoid deprecated and end of life plugins. You want plugins that have activeb maintainers. Good ones of Note are Disvourse Official plugins and Pavilion group; though there are many others that are actively maintained then just these 2 groups I have mentioned.
