Can’t activate and deactivate plugins

First always take a full backup of your site and database before doing anything.

Via FTP rename your Plugins folder to “Plugins_bak” and make another Plugins folder.

Then go to WordPress dashboard try installing any plugin and see if you can activate – deactivate them.

If this works then there must be an issue with one of your plugins.
