I testet it. Enabling in the frontend throws the same message "Error: this app cannot be enabled because it makes the server unstable".

I can enable it over the occ command, after this the server anwers with a Internal Server Error:

{"reqId":"jo59oaUCv3WxAAdX4xDY","level":4,"time":"2018-10-09T08:30:01+02:00","remoteAddr":"","user":"--","app":"cron","method":"--","url":"--","message":"Exception: {"Exception":"Error","Message":"Class 'OCA\\LoginProtect\\Application' not found","Code":0,"Trace":"#0 \/var\/www\/owncloud\/lib\/private\/legacy\/app.php(242): require_once()\n#1 \/var\/www\/owncloud\/lib\/private\/legacy\/app.php(193): OC_App::requireAppFile('loginprotect')\n#2 \/var\/www\/owncloud\/lib\/private\/legacy\/app.php(127): OC_App::loadApp('loginprotect')\n#3 \/var\/www\/owncloud\/cron.php(52): OC_App::loadApps()\n#4 {main}","File":"\/var\/www\/owncloud\/apps\/loginprotect\/appinfo\/app.php","Line":26}"}

I cant disable app per occ, an unhandled exception has been thrown:

Error: Class 'OCA\LoginProtect\Application' not found in /var/www/owncloud/apps/loginprotect/appinfo/app.php:26
Stack trace:

So i disabled it per mysql.
