BadgesOS blank page

Hi Support.

I have BadgesOS integrated with Learndash and BuddyPress and this morning I noticed a bug on the single course pages which looked like this: https://prnt.sc/t19rcc

The page is black with JSON print:

{
   "@context":"https:\/\/w3id.org\/openbadges\/v2",
   "type":"Assertion",
   "id":"\/members\/emailaddressgmail-com\/courses\/?bg=0&eid=0&uid=0",
   "recipient":{
      "type":"email",
      "hashed":true,
      "salt":"BADGEOSOBI",
      "identity":"sha256$ddbc8b27496e2e6991d13816769fd55c169583126e43fab5ea7d282b2df8d73a"
   },
   "badge":"\/members\/emailaddressgmail-com\/courses\/?bg=0&eid=0&uid=0",
   "issuedOn":"2020-06-17T08:31:08+00:00",
   "image":"https:\/\/www.domain.com\/wp-content\/plugins\/badgeos\/images\/default_badge.png",
   "verification":{
      "type":"HostedBadge",
      "verificationProperty":"id"
   }
}

I couldn’t figure out any issue. There are no errors on the page. I disabled the plugin as a temporary solution. Any suggestion as to what could be the issue?
