Fatal error because of a wrong plugin created by me

I'm having the following error message. I know what caused the problem but I can't be able to fix it. When I try enter into File Manager or Plugin functionalities Altervista gives me this error message. So I can't delete the plugin file or desabilitate it. There is any way to fix it. It's a site for study purposes.

Fatal error: Uncaught exception: ParseError: syntax error, unexpected '}', expecting ';' in /membri/fernandaoliveira/wp-content/plugins/f-plugin/A5_FernandaPlugin.php:

Thanks in advance

Did you try the recovery procedure?

Bye!
