Ok, I can reproduce this, you can work around this issue by explicitely calling the content in the default language in your config:

    'ready' => function () {
	    return [
		    'johannschopplich.content-translator' => [
			    // API key for the DeepL free or pro plan
			    'DeepL' => [
				    'apiKey' => site()->content('fr')->DeeplAPISecret()->value()
			    ]
		    ],

		    'owebstudio.instagram-feed' => [
			    'accessToken' => site()->content('fr')->InstagramAccessToken()->value(),
			    'cache' => true,
			    'store' => true,
			    'debug' => false,
			    'expire' => 480, // 3 hours
			    'limit' => 12 // fetch limit
		    ],

		    'hcaptcha' => [
			    'secret' => site()->content('fr')->hCaptchaSecret()->value()
		    ]
	    ];
    },

I’d also recommend to set those token/secret fields to translate: false, you don’t want users to translate them into different languages.
